User Comments:
kevcundick: Using TomEE 1.0, I started it in debug mode.  I set a break on a line to watch for a specific record duirng a loop.  The app does loop a lot of records.  The record I was watching for was part of an object, ex. pt.getLastName().equals("name").  While running the app, it became extreamly slow.  Eventually I had to kill both the TomEE and Netbeans processes.  I can reproduce this problem at will.  I don't usually have problems debugging this way, for some reason it happens in this instance consistently.

Tons of JCClassDecl trees held by DocEnv.treePaths variable. It is declared as WeakHashMap<JCTree, TreePath>, however since every value holds its key (TreePath holds given JCTree at its end), all map entries are held forever. The real pain is that every expression evaluated by debugger adds a new entry to this map.

Fixed in jet-main.
