Mario Ivankovits commented on VFS-156:
--------------------------------------
reg LRUFileCache: I'll deprecate any cache other than the SoftRef, WeakRef as
with any other implementation VFS will leak memory too ... it will never free
the FileSystem map .... if you don't come up with a patch for this too :-)
Even then LRUFileCache is optional.
Might it be sufficient to add a method e.g. hasFileListener(xx) ?
> Use a set to hold the listeners in AbstractFileSystem
