Description
Now that the Assertion Predicate fixes are in, we can re-enable the malformed graph assert which was removed with JDK-8317998. Back there, the Java Fuzzer found a lot of cases related to missing Assertion Predicates which let the assert file. We decided to disable it temporarily to reduce the noise until the issues with Assertion Predicates are fixed - which is now the case.
