As the included jtreg test demonstrates, `StackWalker.getCallerClass()` can throw an `UnsupportedOperationException` if called reflectively. Currently this only happens if we invoke `StackWalker.getCallerClass()` recursively reflectively, but this issue will become more prominent once we fix [JDK-8285447](https://bugs.openjdk.org/browse/JDK-8285447).
