Thank you very much for your prompt responses. Yes, the old JRockit JVM version is the likely
culprit. Initial testing with -XNoOpt has not yet produced the failure, although it is too
early to be certain this fixes it.

I am very interested in attending your talk on testing Lucene/Solr with various JVMs.

>>Finally, I would recommend to use Oracle Java 7 instead of JRockit!

Agreed!

Thanks again
-Lynn

is more than antique). The current one is jrockit-jdk1.6.0_45-R28.2.7-4.1.0. Unfortunately
the later version still have bugs, that may also lead to corrupt indexes. Because of this
we are running nightly tests at the moment only with the "-XnoOpt" setting (we are testing
Lucene/Solr with Oracle, IBM J9 and JRockit), otherwise the tests fail regularly because of
JVM bugs. Those bugs are listed on: http://wiki.apache.org/lucene-java/JavaBugs
