+<h2 class="h3">1. Introduction: The Enterprise Content Integration
Challenge</h2>
+<div class="section">
+<p>
+In modern enterprise environments, valuable unstructured content resides
across dozens of disparate repositories—including Microsoft SharePoint,
Atlassian Confluence, IBM FileNet, EMC Documentum, network file shares,
databases, and cloud platforms like Google Drive and Salesforce.
+</p>
+<p>
+Building an effective search experience across these repositories requires
solving two major challenges:
+</p>
+<ol>
+ <li><strong>High-performance, Incremental Ingestion:</strong> Reliably
extracting documents, metadata, and updates from diverse repositories without
placing undue load on source systems.</li>
+ <li><strong>Document-Level Security (ACL) Enforcement:</strong> Ensuring
that users only see search results for documents they have explicit permission
to access in the source repository.</li>
+</ol>
+<p>
+<strong>Apache ManifoldCF™</strong> is an open-source framework
specifically architected to solve both of these challenges seamlessly.
+</p>
+
+<div class="info-box">
+ <div class="info-box-title">Key Takeaway</div>
+ Apache ManifoldCF acts as an intelligent middleware layer that continuously
crawls source repositories, extracts metadata and security ACLs, and feeds
target search engines (like Solr, Elasticsearch, and OpenSearch) while
maintaining security trimming.
+</div>
+</div>
+
+<a name="N10030"></a><a name="architecture"></a>
+<h2 class="h3">2. Core Architecture & Connector Model</h2>
+<div class="section">
+<p>
+ManifoldCF's modular architecture relies on four distinct types of connectors:
+</p>
+
+<table class="architecture-table">
+ <thead>
+ <tr>
+ <th>Connector Type</th>
+ <th>Role & Functionality</th>
+ <th>Example Connectors</th>
+ </tr>
+ </thead>
+ <tbody>
+ <tr>
+ <td><strong>Repository Connectors</strong></td>
+ <td>Fetch documents, version strings, metadata, and raw content streams
from source systems.</td>
+ <td>SharePoint, FileNet, Documentum, Jira, Confluence, Web, File System,
HDFS, Google Drive</td>
+ </tr>
+ <tr>
+ <td><strong>Authority Connectors</strong></td>
+ <td>Query authentication systems to retrieve active user and group
security tokens for search-time ACL filtering.</td>
+ <td>Active Directory, LDAP, SharePoint Authority, Salesforce
Authority</td>
+ </tr>
+ <tr>
+ <td><strong>Transformation Connectors</strong></td>
+ <td>Process document streams between extraction and indexing (e.g., text
extraction, metadata mapping).</td>
+ <td>Apache Tika, Metadata Extractor, OpenNLP, Content Limiter</td>
+ </tr>
+ <tr>
+ <td><strong>Output Connectors</strong></td>
+ <td>Receive processed document streams and push indexed data and
security tokens to target repositories.</td>
+ <td>Apache Solr, Elasticsearch, OpenSearch, Amazon CloudSearch, Open
Pipeline</td>
+ </tr>
+ </tbody>
+</table>
+
+<p>
+A typical ManifoldCF ingestion job configures a <em>Repository Connector</em>
to pull documents, optional <em>Transformation Connectors</em> to extract text,
and an <em>Output Connector</em> to index data into Solr or Elasticsearch.
+</p>
+</div>
+
+<a name="N10060"></a><a name="security"></a>
+<h2 class="h3">3. Security Trimming & ACL Enforcement</h2>
+<div class="section">
+<p>
+Unlike naive crawlers that ignore document permissions, ManifoldCF captures
the exact Access Control Lists (ACLs) associated with each document.
+</p>
+<p>
+When indexing a document, ManifoldCF attaches security tokens representing:
+</p>
+<ul>
+ <li><strong>Allow Tokens:</strong> Groups/Users allowed to view the
document.</li>
+ <li><strong>Deny Tokens:</strong> Groups/Users explicitly restricted from
viewing the document.</li>
+ <li><strong>Parent/Folder Tokens:</strong> Hierarchical permission
inheritance.</li>
+</ul>
+
+<p>
+At search time, the application queries ManifoldCF's <strong>Authority
Service</strong> using the logged-in user's identity. The Authority Service
returns the user's active security tokens, which are appended to the search
query (e.g., in Apache Solr or Elasticsearch filters):
+</p>
+
+<div class="code-snippet">
+// Example Solr Filter Query generated by ManifoldCF Authority Service
+fq=(allow_token_document:"group_engineering" OR
allow_token_document:"user_john_doe")
+ AND NOT (deny_token_document:"group_restricted")
+</div>
+
+<p>
+This ensures instant, security-trimmed search results with zero latency impact
during query time.
+</p>
+</div>
+
+<a name="N10090"></a><a name="connectors"></a>
+<h2 class="h3">4. Supported Repositories & Output Targets</h2>
+<div class="section">
+<p>
+Apache ManifoldCF ships out-of-the-box support for a vast ecosystem of
enterprise systems:
+</p>
+<ul>
+ <li><strong>Enterprise Content Management (ECM):</strong> EMC Documentum,
IBM FileNet P8, OpenText LiveLink, Microsoft SharePoint.</li>
+ <li><strong>Collaboration & Social:</strong> Atlassian Confluence,
Atlassian Jira, Salesforce, Google Drive.</li>
+ <li><strong>Data Stores & Files:</strong> Windows/Linux File Systems,
HDFS, JDBC/SQL Databases, Web Crawling, RSS feeds.</li>
+ <li><strong>Search & Storage Destinations:</strong> Apache Solr,
Elasticsearch, OpenSearch, Amazon CloudSearch, File Output.</li>

+<div class="section">
+<p>
+We are thrilled to announce the official release of <strong>Apache ManifoldCF
2.31</strong>! 🚀
+</p>
+<p>
+This release marks one of the most significant architectural milestones in the
history of the Apache ManifoldCF project under issue
<strong>CONNECTORS-1784</strong> (<em>Core Performance & Modernization: The
Java 25 Leap</em>).
+</p>
+<p>
+With ManifoldCF 2.31, we have embraced modern Java runtime capabilities,
adopting <strong>Java 25</strong>, introducing native support for
<strong>Virtual Threads (Project Loom)</strong> across the crawling engine,
upgrading our embedded web server stack to <strong>Jetty 12.1</strong>, pruning
tens of thousands of lines of legacy code, and streamlining our Docker and
CI/CD pipelines.

+<h2 class="h3">2. The Java 25 Leap & Virtual Thread Concurrency</h2>
+<div class="section">
+<p>
+Enterprise content integration engines spend a substantial portion of their
execution lifecycle waiting on I/O operations—network latency from HTTP calls,
REST endpoints, database queries, and repository API responses. In traditional
architectures, each worker thread maps directly to an OS platform thread,
consuming significant system memory (stack allocation) and causing expensive
context switching when thousands of concurrent documents are fetched.
+</p>
+
+<div class="info-box">
+ <div class="info-box-title">What Changed in Core Architecture
(CONNECTORS-1784)</div>
+ <ul>
+ <li><strong>CrawlerAgent & Worker Threads:</strong> Document
processing workers and queue dispatchers now utilize lightweight Java 25
Virtual Threads (<code>Executors.newVirtualThreadPerTaskExecutor()</code>).</li>
+ <li><strong>AgentsDaemon:</strong> Central service management converted to
virtual thread execution.</li>
+ <li><strong>Network & Socket Handlers:</strong>
<code>InterruptibleSocketFactory</code>, <code>ThrottledFetcher</code>, and
<code>CommonsHTTPSender</code> were reworked to ensure socket read/write
operations unmount virtual threads cleanly without pinning carrier threads.</li>
+ <li><strong>Authority Servlets:</strong> <code>UserACLServlet</code> now
serves high-concurrency permission check requests using virtual threads.</li>
+ </ul>
+</div>
+
+<p>
+<strong>Performance Impact:</strong> Virtual threads allow ManifoldCF to scale
worker concurrency into thousands of simultaneous fetching operations per node
without experiencing thread starvation or excessive memory growth.

+<h2 class="h3">3. Web Stack Modernization: Jetty 12.1 Integration</h2>
+<div class="section">
+<p>
+To support Java 25 and modern HTTP protocols, the embedded application
container and test harnesses have been updated to <strong>Jetty 12.1</strong>.
+</p>
+<ul>
+ <li><strong>Virtual Thread Connector Engine:</strong> Jetty 12 natively
supports Virtual Thread executors for handling incoming HTTP requests to the
ManifoldCF UI and REST APIs.</li>
+ <li><strong>Updated Servlet Specs:</strong> Aligning with modern Java EE /
Jakarta EE standards.</li>
+ <li><strong>Improved Security & Performance:</strong> Lower connection
latency and better resource cleanup during connector shutdown cycles.</li>
+</ul>
+</div>
+
+<a name="N10070"></a><a name="pruning"></a>
+<h2 class="h3">4. Codebase Pruning: Streamlining Legacy Connectors</h2>
+<div class="section">
+<p>
+Over the years, ManifoldCF accumulated legacy connectors for obsolete or
proprietary systems (e.g., legacy Documentum, FileNet, and Meridio integration
code) requiring legacy third-party SDKs that are no longer available in public
repositories.
+</p>
+<p>
+In 2.31, we conducted a major cleanup, removing <strong>over 88,000 lines of
unmaintained legacy code</strong>:
+</p>
+<ul>
+ <li><strong>Removed:</strong> Legacy Documentum, FileNet, and Meridio
connector modules.</li>
+ <li><strong>Result:</strong> Faster build times with Apache Ant and Apache
Maven, simplified dependency graph, reduced CVE risks, and a smaller Docker
image footprint.</li>
+</ul>
+<div class="info-box">
+ <div class="info-box-title">Active Enterprise Connectors Preserved</div>
+ Active enterprise connectors (such as Solr, OpenSearch, Elasticsearch, CMIS,
Web, JDBC, Google Drive, Amazon S3, SharePoint, Nuxeo, and Generic REST/JSON)
remain fully supported and updated.

+<h2 class="h3">5. Logging & Startup Diagnostics Cleanup</h2>
+<div class="section">
+<p>
+Starting up enterprise daemons should produce clean, predictable log output.
In 2.31, we addressed two persistent logging friction points:
+</p>
+<ul>
+ <li><strong>Log4j Package Scanning:</strong> Resolved deprecation warnings
regarding package scanning in Log4j configuration
(<code>logging.xml</code>).</li>
+ <li><strong>SLF4J Provider Selection:</strong> Fixed missing SLF4J provider
warnings at startup across single-process, multi-process, and Docker
environments.</li>

+<div class="section">
+<p>
+With ManifoldCF increasingly deployed in modern Cloud Native environments
(Kubernetes, AWS ECS, OpenShift), release 2.31 upgrades our infrastructure
stack:
+</p>
+<ul>
+ <li><strong>Official Java 25 Dockerfile:</strong> Updated base images to
Java 25 runtimes.</li>
+ <li><strong>Automated Docker Integration Tests:</strong> Added
<code>docker-integration-test</code> module and GitHub Workflows to validate
end-to-end containerized deployments automatically on every pull request and
release build.</li>
+ <li><strong>Maven & Release Workflows:</strong> Streamlined GitHub
Actions for generating Release Candidates and publishing artifacts to Maven
Central.</li>
