Stackoverflow in CoreASTProvider

This is likely because I had a breakpoint set somewhere. Even still, it would seem like there should be some checks on this recursive loop somewhere, and a better or more checked exception should somehow be thrown here.

Read CoreASTProvider.java, especially getAST at lines 132 and 189, and inspect the "Requesting Java AST from selection" job associated with the stack trace. Trace why getAST re-enters recursively and define done as preventing the unbounded recursion while reporting an appropriate exception; the payload names no test to run.
