Using Hibernate Validator 4.3.1.Final Threads are going in an infinite loop when trying to detect Types:

This is the content of the Map:

{C=E, A=A, E=E}

taken from the normalize Method while debugging stuff.

The code explicitly states this:

                // TODO: will this cause an infinite loop with recursive bounds?

		for ( Entry<K, V> entry : map.entrySet() ) {
 		        K key = entry.getKey();
			V value = entry.getValue();

			while ( map.containsKey( value ) ) {
				value = map.get( value );
			}

			map.put( key, value );
		}

Yes it does result in a infinite loop - it hangs forever in the inner while loop.
Actually we are stuck here - please fix this.
As i am bound to JPA 2.0 i can't try the 5.x line.

The "map.put" while iterating over the map could be changed to "entry.setValue(...)" too.
