The best place to report Lustre bugs is at https://jira.whamcloud.com/

Please include the Lustre version number you are running, and any details you can provide about what kind of IO the Java application was doing at the time, if this is even possible for Java :-). It looks like it is doing AIO?  Also, is this repeatable, or a one-time event?

Cheers, Andreas
