Description Jesse Glick 2008-09-24 00:10:39 UTC 
The value of this WeakHashMap refers strongly to the key, so neither will ever be collected. In general this kind of
problem is unsolvable in Java:

In this case the cache can probably be strong only for layers currently modified in memory, else use SoftReference.

(Found in a heap dump where a NbModuleProject was leaked this way.)
