We walk down O(N) frames.\n\nThis was what was happening with\ncode.google.gson.functional.CircularReferenceTest.

      "message": "Fix exception reporting from interpreter\n\nTo comply with JDWP exception report rules, we must report an exception at the\nlocation of the throw (or the first instruction encountered after a native\ncall). To do this, we use the CatchLocationFinder visitor to look for a catch\nhandler until we reach a native frame or the top frame.\n\nBecause interpreter handles pending exception on a method-by-method basis, we\nneed a flag to remember we already reported the exception and avoid reporting\nit multiple times when unwinding methods. The drawback is we need to maintain\nthe state of this flag. We clear it when the exception is cleared.
