I have deployed a Liferay Portlet which uses GWT and REST. I have this problem
of thread hanging and get a Internal connect Error.. Some times it works but
most of the time i run into this issue..
I am using the latest version of Restlet.
Below is the Thread Dump . Any suggestions on how to fix this ?
