Hi, I understand the .class file after the manipulation has a wrong local variable table but my question is why you think this is a prlbem. Since the local variable table is not used *at all* at runtime, I guess you saw another real problem and decompiled the .class file, and then you found the local variable table contained a wrong entry. Another guess is you are using another tool that refers to the local variable table. In either case, I am happy to fix the bug(?) of Javassist but I would also like to know what is your real problem.
