Description Petr Hrebejk 2002-01-30 12:15:36 UTC 
There seems to be bugs in MDRCache
1) When removing from the cache HasMap the remove method is called with
the value parameter instead of key. This results in not removing the items

2) The get method adds the key into the hardLinks cache even if the key is 
already included in the cache. 20 gets of the same key result in 20 
identical entries in the cache, which is probably not desired

3) I think the base class for the CacheReference should be rather
WeaikReference than SoftReference to be more memory friendly

Cool! How did you spot it? Currently I am refactoring the MDR API a
bit (according to the discussion with Yarda on openide-dev) so I am
not able to validate the patch. I will apply it after I will validate
and commit the changes of the APIs.
