----------------------------------------------------------
I don't understand the build problem. It looks like the {{ServiceLoader}}
initialization isn't happening. I've never seen this before in a build.
It does not look like a simple classpath problem - the main and test code
compiles and starts to run.
I use the same java version and same maven, except Alexis has:
{noformat}
Apache Maven 3.3.9 (NON-CANONICAL_2015-11-23T13:17:27+03:00_root;
2015-11-23T08:17:27-02:00)
{noformat}
whereas I have
{noformat}
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5;

{noformat}
You don't need to build from scratch - though you are welcome to - a clean repo
and building a module should pull in the jars from the Apache snapshots repo.
If building from scratch, you have to build Jena from the top, not module by
module, the first time.
A fast route to get modules up to Fuseki2:
{noformat}
mvn clean install -Pboostrap
mvn clean install -Pdev
{noformat}
as being quicker than the full
{noformat}
mvn clean install
{noformat}
All run in the Jena root directory.

> Slow Model.createList()
> -----------------------
>
> Key: JENA-1290
> URL: https://issues.apache.org/jira/browse/JENA-1290
> Project: Apache Jena
> Issue Type: Improvement
> Components: Core
> Affects Versions: Jena 3.0.1, Jena 3.2.0
> Environment: OpenJDK 1.8.0.121-b13
> Reporter: Alexis Armin Huf
> Priority: Minor
> Attachments: JENA-1290.patch, jena-slow-rdflist.tar.gz,
> mvn-clean-install.log.gz
>
>
> Model.createList(Iterator) is slow for large list sizes. Starting at 128
> nodes, creating a list from an ArrayList iterator takes ~3.6ms and the time
> goes up to 182ms for 1024 nodes. Creating the RDF list by hand and then doing
> .as(RDFList.class) for the 1024-nodes tests takes only 1.2ms. I will attach a
> MWE.
> Going through the code, the cause seems to be that RDFListImpl.with() , which
> is called for every member added, will always walk the entire list to get the
> last node. It mentions a possible cache for that, but it is not implemented.
> I wrote a patch for this issue replacing ModelCom.createList()
> implementation. I could not find tests for createList, so I added three
> simple ones to TestModel.
> PS: I'm having a classpath issue with jena-arq tests on mvn clean install, so
> I could only run tests for jena-core. Are there more specific instructions
> somewhere for building and testing jena?
