JCK            : JCK 7 b10 
J2SE           : FAIL - since jdk 1.7.0 build 27 
Platform[s]    : FAIL - Solaris 10 i586 (x64)
Java options   : FAIL - -Xcomp (may hang with -Xint)

api/java_awt/awt_focus_subsystem/event_delivery/index.html#EventDelivery test (which is new in jck7) hangs with a deadlock when run on solaris x86 (32 and 64 bit jvm) with -Xcomp option. This failure can be traced back up to b27 of jdk7 (for b27 it hangs with -Xint option also). Please see jstack output in comments.

Steps to reproduce:
1. Install jdk (for ex. to /export/jdk/jdk1.7.0)
2. Install JCK7 (for ex. to /export/JCK/JCK-runtime-7)
3. Prepare a simple script to run a test (run.sh) of the following content
#!/bin/bash 

export JAVA=/export/jdk/jdk1.7.0/bin/java
export CLASSPATH="/export/JCK/JCK-runtime-7/classes"

OPTS="-Xcomp" # fails 
TEST="javasoft.sqe.tests.api.java.awt.Event.awt_focus_subsystem.event_delivery.EventDeliveryTests"
