RFR: 8304931: vm/concepts/methods/methods001/methods00101m1/methods00101m1 failures with already pending exception

Mon Mar 27 21:23:12 UTC 2023

The change in [JDK-8304069](https://bugs.openjdk.org/browse/JDK-8304069) resulted in an assertion failure in the case of multiple duplicate fields, methods, or interfaces. This would create unwanted pending exceptions leading to a failure later.

The method will now return following a class file parse error to avoid adding more pending errors. Verified with tiers 1-6.
