[Roman Kennke]

Hi all,

This backports a fix for a memory leak in the JDWP.
The original change applies cleanly:

https://github.com/openjdk/jdk/commit/5ab22e88da8d79f9e19e8afffdd06206f42bab94

See issue:
https://bugs.openjdk.java.net/browse/JDK-8276990
and original PR:
https://github.com/openjdk/jdk/pull/7306

Thanks!
