FULL PRODUCT VERSION :
java version "1.6.0_27"
Java(TM) SE Runtime Environment (build 1.6.0_27-b07)
Java HotSpot(TM) 64-Bit Server VM (build 20.2-b06, mixed mode)

FULL OS VERSION :
Microsoft Windows [Version 6.1.7600]
Linux lintestathon01 2.6.18-194.26.1.el5 #1 SMP Tue Nov 9 12:54:20 EST 2010 x86_64 x86_64 x86_64 GNU/Linux

A DESCRIPTION OF THE PROBLEM :
Starting with java 1.6.0_25, java will crash when running application. Application only crashes in 64-bit mode, 32-bit mode seems fine. We have replicated the problem by running the test case below. Issue is also reproducible in 1.6.0_29.

THE PROBLEM WAS REPRODUCIBLE WITH -Xint FLAG: No

THE PROBLEM WAS REPRODUCIBLE WITH -server FLAG: Yes

REGRESSION. Last worked in version 6u29

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
run "java test.SegFault" with 64-bit 1.6.0_27 release on Windows 7 box

EXPECTED VERSUS ACTUAL BEHAVIOR :
Expect java to gracefully exit after executing all tasks.
