The use of `Optional` was Dale's preferred way for error-handling instead of using `null`. I started out coding this: ``` private static Class<?> classForName(String className) { try { return Class.forName(className); } catch (ClassNotFoundException e) { logger.error("Unable to add class {} to IGNORE_CLASSES", className, e); } return null; } ``` Changing from `null` to `Optional` resulted in: ``` private static Optional<Class<?>> classForName(String className) { try { return Optional.of(Class.forName(className)); } catch (ClassNotFoundException e) { logger.error("Unable to add class {} to IGNORE_CLASSES", className, e); } return Optional.empty(); } ``` These 2 RMI classes fail the various checks in AnalyzeSerializable, and the cause seems to be the `CompiledClass` library in geode-junit's org.apache.geode.codeAnalysis package (which I think was a 3rd party library that was pulled into our test code). All `RMIObjects` fail deserialization checks with an "invalid RMI" failure because the library doesn't know how to handle RMI. If `Class.forName` failed to load `RemoteDUnitVM`, 2 or 3 tests end up failing. I'd like to fix that library but this is for test-only code anyway, so I decided to have it just skip RMI classes. One possibility that I considered was to throw `new RuntimeException(e)` wrapping the `ClassNotFoundException` but I think that will end up throwing a `LinkageError` of type `NoClassDefFoundError` when attempting to load `AnalyzeDUnitSerializablesIntegrationTest`. Yet another approach might be to not use a static constant for the `IGNORE_CLASSES` and just build up a the `Set` every time `ignoreClass` is called. I would be happy to change this to something better, especially if you have any other ideas. -- This is an automated message from the Apache Git Service.
