Hi,

Please review this fix for JDK-8211821.  The change fixes the problem by moving the call to exitglobals() in Threads::destroyvm() to before the thread gets deleted.

I need to give that some very careful thought - this stuff is very fragile and a simple change can have unexpected consequences.

Thanks, David

  Although exit_globals() deletes tty, this is not a

problem because neither deleting thread nor freeing the jvmcioldthreadcounters use tty.

Open Webrev: http://cr.openjdk.java.net/~hseigel/bug8211821/webrev/ JBS Bug:  https://bugs.openjdk.java.net/browse/JDK-8211821 The fix was tested by running the new test and Mach5 tiers 1 and 2 tests and builds on Linux-x64, Windows, and Mac OS X, running tiers 3-5 tests on Linux-x64, and by running JCK-12 API, Lang and VM tests on Linux-x64. Thanks, Harold
