HABA commented on JSPF-112:
---------------------------
Hello [~btellier],
Thank you for the quick response and for proposing the fix.
After applying the changes from PR
[#24|https://github.com/apache/james-jspf/pull/24], the following exception now
appears:
{code:java}
11:56:23.770 [ForkJoinPool.commonPool-worker-1] ERROR

With the previous version, we encountered the following exception instead:
{code:java}

11:59:30.628 [dnsjava NIO selector] DEBUG org.xbill.DNS.NioClient -- dnsjava

While the timeout issue seems to be addressed, it would be helpful to receive
an exception message that clearly indicates the absence of an SPF record,
similar to the {{NoneException}} we received previously. This would improve the
clarity of the error handling and help in diagnosing issues.

> Project: James jSPF
> Issue Type: Bug
> Components: Core
> Environment: WIN SERVER 2016, JAVA 17.0.10
> Reporter: HABA
> Priority: Blocker
> Time Spent: 10m
> Remaining Estimate: 0h
>
> When performing an SPF check using
> org.apache.james.jspf:apache-jspf-resolver:1.0.4, the process hangs
> indefinitely during the DNS resolution phase. The issue is observed with the
> following SPF check:
> {code:java}
> String spfResult = new
> DefaultSPF().checkSPF("207.54.72.202","[email protected]","esa13.hc437-5.eu.iphmx.com").getResult();{code}
> The log indicates the process gets stuck at the A-Record lookup for the
> domain 207.54.72.202.spf.hc210-93.eu.iphmx.com, with repeated debug messages
> until it eventually times out after multiple hours:
> {code:java}

> *Steps to Reproduce:*
> Use org.apache.james.jspf:apache-jspf-resolver:1.0.4.
> Perform the SPF check with the provided code snippet.
> Observe the logs and notice the process getting stuck at the DNS
> resolution step.
> *Expected Result:*
> The SPF check should complete without hanging, as it does in version 1.0.3.
> *Actual Result:*
> The SPF check hangs indefinitely during DNS resolution, eventually timing out
> after several hours.{*}{*}
> *Version:* org.apache.james.jspf:apache-jspf-resolver:1.0.4
