Created attachment 141552 [details] proposed patch In the constructor of WeakListenersImpl.ProxyListener there is an unsynchronized access to a static WeakHashMap. WeakHashMap itself is not threadsafe and must be wrapped in a synchronized container to prevent data structure corruption. The corruption has the effect of a tight loop and thus blocks the Thread. Not a deadlock but bad nonetheless. Multi-threaded calls to public static <T extends EventListener> T create(Class<T> lType, Class<? super T> apiType, T l, Object source) can lead to said corruption and block the caller Thread. The attached patch wraps the WeakHashMap in a synchronized Map and thus fixes this defect.
