Hi all,

could you please review this patch which open sources JDB tests from VM testbase?

these tests were developed to test 'jdb' tool and JDI thru it.

As usually w/ VM testbase code, these tests are old, they have been run in 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.

JBS: https://bugs.openjdk.java.net/browse/JDK-8199379
webrev: http://cr.openjdk.java.net/~iignatyev//8199379/webrev.00/index.html
testing: :vmTestbase_nsk_jdb test group

Thanks,
-- Igor
