This is done because GC needs to have contiguous address range for the heap, and allocates virtual address range upfront. > $ ./java Hello > WARNING: final heap size is too large, reduced to 900 Mb > Hello The size is as low as 900 Mb on my laptop most probably due to some DLL sticking in the middle of the process address space. I saw DRLVM working with 1300m heap on some other machine. What's more, there exists an unpleasant side effect of "infinite" -Xmx. If you have a leaky native library (and we had!), then the amount of memory available to the C heap is minimized, and the time range before your program crashes becomes much shorter. I saw Eclipse crashing after 1 hour with -Xmx1g, but working for more than a day with -Xmx600m, which left 400m more megabytes to native heap. --------------------------------------------------------------------- Terms of use : http://incubator.apache.org/harmony/mailing.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
