I've posted one comment.
Otherwise, it looks okay to me.
Also, the debugger needs to be tested with mach5 on all platforms.

This test was problem listed on mac-osx (the reason was this bug https://bugs.openjdk.java.net/browse/JDK-8282383) before Leonid problem listed it generally. So we want to restore this? Also, this test is failing with timeout when I run it locally on linux-x64-debug.
