Hi, I'm using Javassist 3.4 for building a disassembler java bytecode like javap tool. When the bytecode contains instructions like "iinc_w", it is shown like "wide". My method for disassembling is checking the current pc with next() and looakAhead() methods from CodeIterator class and the difference between them gives me the bytes for reading with byteAt() method. I've also tried with s16bitAt() and s32bitAt() methods but they does not show mnemonics correctly. What is wrong? Is there any form to read correctly these instructions? Best regards. Ulises.
