This is really weird. Might be time to file a bug report with Sun. > - Does this indicate some kind of threading problem in this Java env? Hard to tell without a snapshot of what's going on inside the GC code (which is all C++, not Java). Could also be a problem with Ubuntu. > - Does the option "DoEscapeAnalysis" still use a parallel gc? Should be independent of the GC algorithm; it's extra logic in the JIT that determines whether or not an object even needs to be allocated, or if it can simply reside on the method's stack. > - Is the experimental more similar to the parallel or the serial? My understanding is that G1GC is both parallel and concurrent. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
