IBM Worklight 6.2: JMX configuration error. Unable to obtain MBeans - ibm-mobilefirst

Question

I have IBM Worklight 6.2 development environment with the following setup.
Oracle Java 1.7
Eclipse 4.3
IBM Worklight 6.2 Developer Edition
A sample Hybrid project had been created and deployed in the Worklight development server and app works fine in the Mobile Browser Simulator.
I am getting the following error in Worklight Server console in Eclipse:
[ERROR ] Failed to obtain JMX connection to access an MBean.
There might be a JMX configuration error: Read timed out
[ERROR ] FWLSE3000E: A server error was detected.
FWLSE3012E: JMX configuration error. Unable to obtain MBeans. Reason: "Read timed out".
And also I am getting the following error in Worklight Console[Web Console].
FWLSE3012E: JMX configuration error. Unable to obtain MBeans. Reason: "Read timed out".
Note:
I have read the following questions but no luck.

Additional Info:
I used to get the following error whenever the Worklight development server is started from eclipse.

The JMX timeout error in Worklight 6.2 is a known issue.
Typically when this error occurs to me, a way to resolve it is to either 'wait' a while and then to stop & restart the Worklight Server (in Eclipse > Servers view > 'play' button). Another option is to restart Eclipse.
You can also try the suggestions from the comments:
Try to edit the file
WorklightServerConfig/servers/worklight/jvm.options in your Eclipse
workspace, adding the line
"-Dcom.ibm.ws.jmx.connector.client.rest.readTimeout=180000". Then stop and restart the Worklight Development Server.
and
Try to edit the file
WorklightServerConfig/servers/worklight/server.xml and add in the
section the following line, then restart and try again:
<executor name="LargeThreadPool" id="default" coreThreads="40"
maxThreads="80" keepAlive="60s" stealPolicy="STRICT"
rejectedWorkPolicy="CALLER_RUNS" />
Best is to open a PMR (support ticket) and request an iFix as this is due to be fixed.
