IndexMerger throws null pointer exception without stacktrace
------------------------------------------------------------
Key: JCR-2071
URL: https://issues.apache.org/jira/browse/JCR-2071
Project: Jackrabbit Content Repository
Issue Type: Bug
Affects Versions: 1.5.0
Environment: Windows OS (XP, Vista)
Linux RHEL
Reporter: Chris Schmidt
I get the following errors in my log file randomly. It seems to happen most
often when creating the lucene indices, but has happened at other times as well:
[IndexMerger] ERROR - Error while merging indexes:
java.lang.NullPointerException
The code at org.apache.jackrabbit.core.query.lucene.IndexMerger line 344
appears to be the point where the error is logged, but no other information is
provided because the throwable isn't sent to the log (only the toString()
version of the exception). I haven't been able to tell if any indexes are
corrupt when this happens.
I suggest that the logger be changed to determine where the null pointer is
coming from first, then resolve the actual issue that is occurring.
