It is a bug, but I saw it only on Windows with my new class pointer patch. I could not reproduce it with the standard JVM, but I did not try very hard. Bug could lead to crashes. Performance impact is nil, since if we do actually run with an encoding scheme mismatch, we won't live very long. If we don't, it does not matter.
