In classFileParser.cpp, we inject ACC_IDENTITY to class and inner class access flags for legacy classes. These injected ACC_IDENTITY appear written as-is to class bytes for instrumentation (JvmtiClassFileReconstituter), which causes disparity due to newly-set bits for older bytecode formats.

This problem was less severe in classes because ACC_SUPER is set to a good default (only for classes). However, for inner classes, the 0x20 bit is undefined before JEP 401, and the problem surfaces there.
