This timeout happens on older/slower machines; mostly Solaris SPARC
machines, but some Win* machines.
Comments
I was able to reproduce this problem on my linux-amd64 NB with the fastdebug build. Getting the Jvmstat counters is much slower and it could easily lead to timeout with the default 2 minutes. I would propose increasing the timeout to 10 minutes - hopefully this will leave enough time for the test to finish even on slower machines.
