Hi,
i'm caching an instance of  javax.xml.ws.Service.
I cache the results of getPort in a ThreadLocal.
When i use multiple parallel asynchronous invocations, this approach does not seem to work, so i invoke getPort for each asynchronous invocation.
I have 8 threads using a web service running in parallel on a i7.
After about 20h of work, all my worker threads are hanging on:

"pool-41-thread-7" prio=10 tid=0x00007f8cc469d400 nid=0x156a runnable [0x000000004691a000..0x0000000046921ba0]

        at com.spratpix.subdomains.ThreadLocalWebserviceProxy.getAsyncPort(ThreadLocalWebserviceProxy.java:47)

Here is how i use getPort


	protected T getAsyncPort() {
		long t0 = System.nanoTime();
		try {
			return service.getPort(portClass, new FastInfosetFeature());
		} finally {
			long dt = System.nanoTime() - t0;
			TimingInterceptor.callChain.addInvocationWithMethod(method, dt);
		}
	}


And the problematic web service call seems to be

	public Future<Boolean> PutFileAsync(String domain, String type, String filename, S3Object file, AsyncHandler<Boolean> asyncHandler);
