Description
As Hotspot Express testing effort, I saw there are a lot of failures due to hanging in a particular app across Linux and Solaris platforms. The time it took varies from minutes to a couple of hours.
But after I attached Jconsole to the hanging processes, the app resumed running for a short while and then hanged again.

Note the failures do not happen to the regular product VM, but only to the VM that will be used in HS Express below.

Java Version: 
Java(TM) SE Runtime Environment (build 1.6.0_02-b05)
Java HotSpot(TM) Tiered VM (build 20070615124853.et151817.baseline, mixed mode)

Flags: 1) "-server  -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:+ShowMessageBoxOnError -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+DisableExplicitGC -Xmx256m", 
2) "-d64  -XX:+UseSerialGC -XX:+ShowMessageBoxOnError -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+DisableExplicitGC"

EVALUATION This appears to be caused by an omission in the fix for 6549267. That problem has resulted in other hangs being observed (see 6572927). The suggested fix addresses the hang observed with 6572927 but has not yet been tested on the "BigApps".
