[SNMP4J] Mpv3.setLocalEngineID

[kenping]

Hi, Frank
    Why do validate the member field localEngineID in here, but not but not 
the method param engineID? Is it a bug?

  public void setLocalEngineID(byte[] engineID) {
    if ((localEngineID == null) ||
        (localEngineID.length < MINLEN_ENGINE_ID) ||
        (localEngineID.length > MAXLEN_ENGINE_ID)) {
      throw new IllegalArgumentException("Illegal local engine ID");
    }
    this.localEngineID = engineID;
  }

I changed it to:
    if ((engineID == null) ||
            (engineID.length < MINLEN_ENGINE_ID) ||
            (engineID.length > MAXLEN_ENGINE_ID)) {
          throw new IllegalArgumentException("Illegal local engine ID");
        }

Yours sincerely,
