Bug 82041 [misc] ClassFileEditor uses generic names for method arguments when source info is available in class file
Version: 3.1.0 Build id: 200412210800 When you open a class file that has no source attachment but has full debugging information the editor does not show the real names of method arguments. 1. Open a class file editor on a class file that does not have a source attachment but has local variable debugging info. 2. Notice that the method arguments have generic names "arg<n>" ClassFileEditor is not asking the class file reader to look in the method bodies for info. In ClassFileEditor#updateCodeView, change: int flags= IClassFileReader.FIELD_INFOS | IClassFileReader.METHOD_INFOS | IClassFileReader.SUPER_INTERFACES; to: int flags= IClassFileReader.FIELD_INFOS | IClassFileReader.METHOD_INFOS | IClassFileReader.METHOD_BODIES | IClassFileReader.SUPER_INTERFACES; It doesn't appear to parse all of the byte code of the method bodies so it shouldn't slow things down too much for large class files.
