This might or might not occur, it seems to happen more easily with the launcher because it kick-loads the workflow's classes faster than if you are slow and waiting for the GUI to load - at least the classes load in a different order.

Stian,

Can you comment on whether this has been reported by any users (or just by us internally). I think it should be considered for the next release; but a lot of this depends on how easy it is to reproduce. I'm a bit confused by your last comment - I think you mean it is reproduced only some times - did you only see it once? June.

Back-assigning to Tom (as T2 project lead) until they are prioritised up for actual implementation

I don't believe this is a problem anymore in 1.7

Probably fixed in latest 1.7-SNAPSHOT of Raven, it avoids multiple calls to findClass by using a lock from the map findClassLocks - also it will do this bit in the end: 
synchronized (classMap) {
			if (!classMap.containsKey(name)) {
				classMap.put(name, loadedClass);
			} else {
				Class otherClass = classMap.get(name);
				if (otherClass != loadedClass) {
					logger.error("Duplicate class loading of " + otherClass);
					logger.error("Returning cached " + otherClass
							+ " instead of loaded " + loadedClass);
					loadedClass = otherClass;
				}
			}
		}

I think I got a deadlock on this old bug today:

Notice the last line from Java:

Found 1 deadlock.
