+Compilation succeeded: 1 warning(s)
+
+---
+
+It's also not good that the compilation proceeds...
+
+
+Steps to reproduce the problem:
+1. do 'make test-local' in mcs/mbas/Test/misc
+
+Actual Results:
+Above shown exception
+
+Expected Results:
+Just a good compilation
+
+How often does this happen? 
+With current svn HEAD, always
