RFR(S): 6542634: TEST BUG: MISC_REGRESSION tests need to have minimum timeouts examined

[Yekaterina Kantserova]

Hi,

Could I please have a review of this fix.

In this fix I take an opportunity to refactor sun/tools/jinfo/Basic.sh and to add more tests for jinfo utility. sun/tools/jinfo/Basic.sh is a last unstable test among tests listed inhttps://bugs.openjdk.java.net/browse/JDK-6542634  that's why I've chosen to use this bug number instead of creating a new one.

bug: https://bugs.openjdk.java.net/browse/JDK-6542634
webrev: http://cr.openjdk.java.net/~ykantser/6542634/webrev.00/

The tests have been run and passed on all basic platforms.

Thanks,
Katja
