  "message": "This addresses issue #622.  The problem is that CastOptimizer leaves the\ntree in a particular state, namely:\n\"Cast.throwClassCastExceptionUnlessNull(value).value\".  The expectation is\nthat FixDanglignRefsVisitor would replace the \".value\" field reference\nwith \".nullField\".  The problem is, however, that only TightenTypesVisitor\ncan force FDRV to run; CastOptimizer cannot.\n\nMy fix is to eliminate CastOptimizer altogether and move its work (mostly)\ninto TypeTightener.  Impossible casts are replaced in the tree with a\n(\u003cnull\u003e) cast, which becomes a throwClassCastExceptionUnlessNull() in\nCastNormalizer.\n\nReview by: mmendez\n\n\n\ngit-svn-id: https://google-web-toolkit.googlecode.com/svn/trunk@403 8db76d5a-ed1c-0410-87a9-c151d255dfc7\n",
