[jira] Commented: (DIREVE-329) JDBM - ArrayIndexOutOfBoundsException

["Simon Temple (JIRA)" <di...@incubator.apache.org>]

    [ http://issues.apache.org/jira/browse/DIREVE-329?page=comments#action_12364198 ] 

Simon Temple commented on DIREVE-329:
-------------------------------------

This appears to be a problem with IBMs java optimisation.

The JVM was being invoked with -opt40

    -X  -opt<number>      optimization level for java program 0(interpret), 10,30, 40

The problem does not occur when optimisation is set to 10 or is not used.

Not using optimisation is now IBMs recommend approach as the JIT will execute code up to 15% faster than that executed with optimisation level 40!

I suggest this issue is closed.
