Pass exceptions thrown by user-provided MatchProcessors back to the user in the form of a new unchecked exception type, MatchProcessorException.
If a MatchProcessor throws an unchecked exception, scanning continues and MatchProcessors are still called for other matches that are found. However, all exceptions thrown by MatchProcessors are packaged up as a list inside a MatchProcessorException, and the MatchProcessorException is thrown as an unchecked exception at the end of the scan. If necessary, the individual exceptions that were thrown by MatchProcessors may be fetched using MatchProcessorException#getExceptions(). (If calling FastClasspathScanner#scanAsync() rather than FastClasspathScanner#scan(), the MatchProcessorException will be wrapped in an ExecutionException when calling Future<ScanResult>#get() on the returned Future.) Individual exceptions thrown by MatchProcessors are also logged during the scanning process, and may be viewed by calling FastClasspathScanner#verbose() before #scan().
