[Checkers] [Fwd: hg: jdk7/tl/langtools: 6663588: Compiler goes into infinite loop for Cyclic Inheritance test case]

[Matt Papi]

Here's another infinite loop that we should check for in the framework 
once JSR 308 javac gets this patch. The URL below has both the patch and 
a test case. (We can't test for it yet, since an unpatched javac gets 
caught in the loop before annotation processing occurs.)

FYI: Sun has just started making commits to their langtools repository 
this morning, and commit messages (like the one below) are forwarded to 
the compiler discussion list (compiler-dev). I plan to forward to this 
list the tiny percentage of commit messages that are interesting to us 
as checker & framework developers, and also add a test case and/or note 
in the bugs file (once I get the bugs file in SVN).
