Jerry Cwiklik created UIMA-5529: ----------------------------------- Summary: 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: 2.1.0-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 fixed 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 serialization of the Exception object and instead using this: StringWriter sw = new StringWriter(); t.printStackTrace(new PrintWriter(sw)); serializedCause = sw.toString(); where t = AnalysisEngineProcessException The entire stack trace is captured as String, wrapped in 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
