pp += 2; Review comment: On one hand, it would be easier to use ASM. On the other hand, ASM cannot handle new classfiles - we could workaround that by downgrading the versions of the classfiles sent to ASM; it would also mean to place ASM into the agent path, or doing some trampoline from the agent to a normal module. I guess I'd try with the handcoded bytecode patcher, and we'll see what are the experiences with that. -- This is an automated message from the Apache Git Service.
