RFR (S): 7185591: jcmd-big-script.sh ERROR: could not find app's Java pid.

[Yekaterina Kantserova]

Hi,

Could I please have a review of this fix.

In this fix I've rewritten sun/tools/jcmd/* tests in pure java to get 
rid of all intermittent failures depending on for example MKS or race 
conditions (test application has not yet started when the test start to 
run).
