Jerry Cwiklik updated UIMA-5529:
--------------------------------
Fix Version/s: (was: 2.1.0-Ducc)
2.2.1-Ducc
> DUCC: Serialization of AnalysisEngineProcessException fails in JP
> -----------------------------------------------------------------
>
> Key: UIMA-5529
> URL: https://issues.apache.org/jira/browse/UIMA-5529
> Project: UIMA
> Issue Type: Bug
> Components: DUCC
> Reporter: Jerry Cwiklik
> Assignee: Jerry Cwiklik
> Fix For: 2.2.1-Ducc
>
>
> If AE process() fails, the JP tries to serialize the exception before sending
> it to the JD. The AE throws a UIMA core AnalysisEngineProcessException which
> fails to serialize with:
> java.io.NotSerializableException: sun.misc.Launcher$AppClassLoader
> It turns out that this is caused by changes made to the
> InternationalizedException class as described in JIRA
> https://issues.apache.org/jira/browse/UIMA-4793
> The fix discussed in the JIRA broke serialization of uima exceptions. The
> InternationalizedException class contains a member variable of type
> ClassLoader which is not Serializable.
> For Ducc, the fix is to avoid Object serialization of the
> AnalysisEngineProcessException and use this instead:
> StringWriter sw = new StringWriter();
> t.printStackTrace(new PrintWriter(sw));
> serializedCause = sw.toString();
> where t = AnalysisEngineProcessException
> The entire stack trace is captured as a String then wrapped in a java
> RuntimeException and sent to the JD for logging.
> Also, add a new job to the DUCC_HOME/example/simple 1-error.job which forces
> AE to throw an error.
