Chris Schmidt updated JCR-2071:
-------------------------------

    Attachment: IndexMerger.patch

Patch to switch the logger to take in the throwable, not just the name of it.

> 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.
