RFR(S): 6977426: sun/tools tests can intermittently fail to find app's Java pid

[Yekaterina Kantserova]

Hi,

Could I please have a review of this fix.

bug: https://bugs.openjdk.java.net/browse/JDK-6977426
webrev: http://cr.openjdk.java.net/~ykantser/6977426/webrev.00/

java/util/logging/LoggerWeakRefLeak.sh and 
java/util/logging/AnonLoggerWeakRefLeak.sh are merged and rewritten in 
java. sun/tools/common/CommonTests.sh is removed because it doesn't test 
the product but sun/tool/common library functionality.

Thanks,
Katja
