Question

I am using LinkedBlockingQueue for my threadPool

new ThreadPoolExecutor(20, 
                       21, 
                       10,
                       TimeUnit.SECONDS, 
                       new LinkedBlockingQueue<Runnable>())

and i suffer from the memory leak Bug (the memory is full of LinkedBlockingQueue Nodes , slowing down gradually), which is fixed in JDK 7.

I dont want to change the run time environment or my JDK for now.

LinkedBlockingQueue has no size limit , unlike the other implementations of BlockingQueue Interface. Can you suggest any alternative queue ?

The fix bug-id you link to has also been backported to Java 6. It has been fixed in Java 6 since Java 6 Update 19, see https://bugs.java.com/bugdatabase/view_bug?bug_id=2186685 (this one is BTW linked on the bug you refer to).
