Subject CorruptIndexException workaround in 2.3-SNAPSHOT? (Attn: Michael McCandless)
Date Fri, 26 Sep 2008 00:09:53 GMT
According to https://issues.apache.org/jira/browse/LUCENE-1282?focusedCommentId=12596949#action_12596949
(Sun hotspot compiler bug in 1.6.0_04/05 affects Lucene), a workaround
for the bug which causes the CorruptIndexException was put in to the
2.3 branch and 2.4.
However, we are still experiencing this issue (intermittent creation
of a corrupt index) with a 2.3-SNAPSHOT from maven.
Was the workaround put into 2.3-SNAPSHOT?  Are there other issues
which would cause the same error (detailed below)?

We would prefer to avoid upgrading to JDK 6u10
(http://java.sun.com/javase/downloads/ea/6u10/6u10RC.jsp) until it is
a final release, thus the use of the 2.3-SNAPSHOT dated July 22.


Detailed error (seems to match LUCENE-1282):
[java] org.apache.lucene.index.CorruptIndexException: doc counts
