java - Is it possible to set breakpoints at a specific bytecode instruction? -

-

i'm using jdb remotely debug java application of don't have source code. furthermore, application jars obfuscated.

i can set method breakpoints but, possible set breakpoints @ specific bytecode instruction within method? idea have use disassembler javap identify interesting instructions.

can jdb or other java debugger this?

you need line numbers breakpoint on (something assume has been removed). can artificially add line numbers file using instrumentation , able breakpoint @ every instruction if wish.
