Uwe 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!
