Hi all,

could you please review the patch which open sources monitoring tests from vm testbase?

The tests were developed to test hotspot related JMX functionality. as w/ common VM testbase code, these tests are old, they have been run from hotspot testing for a long period of time. originally, these tests were run by a test harness different from jtreg and had different build and execution schemes, some parts couldn't be easily translated to jtreg, so tests might have actions or pieces of code which look weird. in a long term, we are planning to rework them.

testing: vmTestbase_nsk_monitoring test group

Thanks,
