[news.eclipse.tools.jdt] JavaModelCache and how to shrink it

[Gary Karasiuk <karasiuk@xxxxxxxxxx>]

I am looking at two different heap dumps, for the same small scenario. The first one is based on Eclipse 3.2.2 and the second is based on 3.4.2.

The live heap is much larger in the 3.4.2 version. I noticed there is an object called JavaModelCache and it is holding on to 64 MB. In 3.2.2 this object is holding onto less than 1 MB.

1) Any ideas why this has grown so much between 3.2.2 and 3.42?
2) Is there anything that I can do to force the cache to release some of this memory?
