use jd-gui 1.4.0 Decompile a class, but one of the methods is displayed as a byte code

[oicq1699]

use jd-gui 0.3.6 decompile source code:

  public boolean initServer()
  {
    boolean result = false;
    initServerLock.lock();
    try
    {
      if (systemStatus.getStatus() == 0) {
        result = true;
      }
      result = initServer(true);
    }
    finally
    {
      initServerLock.unlock();
    }
    return result;
  }

use jd-gui 1.4.0 decompile source code:

From what I've read here, jd apparently has known issues with try/finally blocks.

[oicq1699]

I think you're right.

May be related to #75.

Duplicate of #37.

Could you share your class to take a look ?

[oicq1699]

I write simple class ,when use finally keyword , This error will reappear
source code:

public class TestJdError {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
            try{
                System.out.println("aaa");
            }catch(Exception ex){

                ex.printStackTrace();

            }finally{
                System.out.println("bbb");
            }
    }

use jd-gui 1.4.0 decompile source code:

public class TestJdError
{
  /* Error */
  public static void main(String[] args)
  {
    // Byte code:
