So some InnerClass entries may sadly be produced for classes that were only used inside method bodies. Possibly an improvement for the future to do more aggressive cleaning. (In general, recording more/unnecessary classes in the InnerClasses shouldn't be harmful besides wasting space, I believe.)

Good to know; thanks Jan.
