EnquireLink doesnt work only bind is and no message is submitted and after 5 min connection is lost

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run SimpleSubmitExample.java
2. Comment out shortmessagesubmit line
3. Remove unbind line also from the code
4. Dont submit any message for more than 5 min 

What is the expected output? What do you see instead?
We should have connection status as bind and enquirelink should work after
5 sec 

What version of the product are you using? On what operating system?
Tested jsmpp-2.0 and jsmpp-2.0.1  OS opens Suse 
Bind connection was possible  but after 5 min connection was lost .

Please provide any additional information below.
Patch 
First part of the patch is been fixed in recent version of setting
setSoTimeout before PDUReaderWorker().start() is made

  */
    public String connectAndBind(String host, int port,
            BindParameter bindParam, long timeout)
            throws IOException {
        logger.debug("Connect and bind to {} port {}", host, port);
        if (sequence().currentValue() != 1) {
            throw new IOException("Failed connecting");
        }

        conn = connFactory.createConnection(host, port);
        logger.info("Connected");
        conn.setSoTimeout(getEnquireLinkTimer());
        sessionContext.open();
        try {

Second patch is to check for the equireLink is null or not 

private void notifyNoActivity() {
            logger.debug("No activity notified");
            if (enquireLinkSender != null) {
                enquireLinkSender.enquireLink();
            }
        }
