Hi,

JRockit is unfortunately very buggy with Lucene, especially this very old version (1.6.0_03
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

You might also be interested on the following talk: http://www.berlinbuzzwords.de/sessions/testing-lucene-and-solr-various-jvms-bugs-bugs-bugs

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

Uwe
