Xiao-Feng Li commented on HARMONY-3993:
---------------------------------------

I found GCv4.1 breaks lusearch as well in 7 iterations sometimes. 

Btw, the gc_common.cpp in above comment is under gc_gen/src/common/.

> I found the vm reports assertion failure when doing enumeration recently. 
> To reproduce the bug easily, you can check out revision 542129 to get the code that is easy to reproduce the bug. Change one line of code in gc_common.cpp (line:49) to permit a 16MB minimal heap size, which helps to reproduce the bug:
> - POINTER_SIZE_INT min_heap_size_bytes = 32 * MB;
> +POINTER_SIZE_INT min_heap_size_bytes = 16 * MB;
> and use the following command line:
> java.exe -Xms16m -Xmx16m -cp . -s large lusearch
