Hello, I thik the underscores in method and field do not match very the other names in that file (or the JCL).
If I understand right, this is an optimization for the case a security manager is not present? For the other case, maybe having absolute but not canonical file names is an option? Or maybe have a special optimization for JAVA_HOME prefixed names? Or does it help in that case as well?
