I decompiled the dex file, but not the Java Class file.

I suppose this is diverging a little from the original comment (which was in the context of an Android application), but surely if running `strings` on the class file found the method, class and field names then it would also find the local variable name too, if it was there.

If I specifically compile the java file with `javac -g:vars DecompilationTest.java` then the local variable name IS included in the file. It is not by default.
