Question

In my bytecode instrumentation project, I stumble frequently on VerifyErrors. However, the default java Verifier gives little information on which instruction resulted in the error (it only gives the method and a small message). Is there any stand-alone bytecode verifier which provides with a little more advanced help in locating the error, at least the precise instruction location? Thank you.

As with any project involving JVM bytecode, I would first check to see whether the BCEL has anything that might be useful for you. Also, perhaps FindBugs may help – though I’m not sure whether it assumes verifiable bytecode to start with or not.
