stack commented on HBASE-2039:
------------------------------
The G1 in 1.6 fails for me in concurrent utils package with a regularity,
something it doesn't do in 1.7. I get further when I use jdk7. Maybe try it?
I did a search on 'IGSEGV (0xb) at pc=0x00007f05f888f201, pid=19186' It turned
up a few hits. Were you running on xen? There is also this:
