Found 1 deadlock.
Note: In J2SE 6.0, the deadlock detection algorithm works only with the locks that
are obtained using the synchronized keyword. This means that deadlocks that arise
through the use of the java.util.concurrency package are not detected.
In the deadlock output, you can see that the thread main is the locking object
<0xf0c30560>, and is waiting to enter <0xf0c41ec8>, which is locked by the thread
“AWT-EventQueue-0”. However, the thread “AWT-EventQueue-0” is also waiting
to enter <0xf0c30560>, which is in turn locked by “main”.
