Right, but there's no need for an external lib, when you can just do: Collections.synchronizedMap(new HashMap())

However I thought that the reason for your complaints was that in the end a non-threadsafe HashMap was used in the original code. Having both get and put being done to it from many threads could possibly lead to more serious errors than just an unnecessary compilation, isn't that so? And for that reason I suggested the ConcurrentHashMap (rather than a Hashtable or similar) to avoid synchronization congestion.
