Examples of javassist.bytecode.CodeAttribute.computeMaxStack()

javassist.bytecode.CodeAttribute.computeMaxStack()
Computes the maximum stack size and sets max_stack to the computed size. @throws BadBytecode if this method fails in computing. @return the newly computed value of max_stack

        CodeAttribute ca = code.toCodeAttribute();
        ca.setMaxLocals(4);
        ret.setCodeAttribute(ca);
        ret.setAccessFlags(AccessFlag.PUBLIC | AccessFlag.SYNTHETIC);
        try {
            ca.computeMaxStack();
            file.addMethod(ret);
        } catch (DuplicateMemberException e) {


        } catch (Exception e) {
            throw new RuntimeException(e);
