On a local linux-x64-debug build this test consistently runs in less

On the mach5 testing machines there was a large fluctuation in the
time to complete this test.
Since the test runs jps with different combinations of arguments, the
total
test time is dependent on the number of processes running java programs.
Since the mach5 test infrastructure runs java programs I have seen a 3X
in the amount of output the test produces compared to local test
runs.
I've run the test several hundred times through mach5 on the slower
platforms
and then examined the test logs using a 3X setting from the default
120 second
jtreg timeout. The slowest reported elapse time from the test logs showed
280 seconds to complete.
To improve the reliability of the test to complete, I'd like to
increase the
timeout to 360 seconds.

Thumbs up! And trivial.
