还是关于java反编译那些经过Java混淆编译器的代码，望高人指点

代码如下：
 public int activeTest(socketStruct socket, int retryTimes, int timeout, deliverVector deliverQueue, int type)
    {

        socketStruct socketstruct = socket;
        socketstruct;
        JVM INSTR monitorenter ;
        int j = 0;
_L4:
        int startTime;
        if(j >= retryTimes)
            break; /* Loop/switch isn't completed */
        startTime = (int)(System.currentTimeMillis() / 1000L);
        head.sequenceId = socket.seq++;
        if(socket.seq == 0x7fffffff)

        if(send(head, body, dataSend) != 0)
        {
            errorCode = 97;
            break MISSING_BLOCK_LABEL_275;
        }
_L2:
        Hashtable hash;
        int i;
        if((int)(System.currentTimeMillis() / 1000L) - startTime > timeout)
            break MISSING_BLOCK_LABEL_275;
        hash = receive(socket);
        if(hash == null)
        {
            errorCode = 22;
            break MISSING_BLOCK_LABEL_275;
        }
        if(!((String)hash.get("result")).equals("ok"))
            break; /* Loop/switch isn't completed */
        SMGPHeadStruct h = (SMGPHeadStruct)hash.get("head");
        if(h.sequenceId != head.sequenceId || h.requestId != head.requestId + 0x80000000)

        if(true) goto _L2; else goto _L1
_L1:

        if(true) goto _L4; else goto _L3
        IOException ioexception;
        ioexception;
        System.err.println("socketLogic.activeTest Failed I/O: ".concat(String.valueOf(String.valueOf(ioexception))));
        startTime = 97;
        socketstruct;
        JVM INSTR monitorexit ;
        return startTime;
