I am running with the = G1 garbage collector (-XX:+UseG1GC). More details below. My question: what to do now? What information do I need to provide for = someone to fix this problem? How do I get this information? Also: should I file a bug report? I will re-run using the regular GC to see if this is perhaps G1 related.
