Chris Laprun commented on GTNPORTAL-1664:
-----------------------------------------
I don't have a definite way to reproduce the issue but I've seen it happen with
WSRP portlets when there's a problem with the remote producer. Note, though, that you
shouldn't need to reproduce the issue to fix it. It's just a matter of not
assuming the portletOfferedPortletContext is not null when producerOfferedPortlet is,
because as mentioned in my original description, when one is null, the other most likely
is as well. :)

Basically, in the following code:
if (producedOfferedPortlet == null)
{
log.info("Could not find portlet with ID : " +
producerOfferedPortletContext.getId());
return null;
}
it's very likely that if producerOfferedPortlet is null, then the associated context
is as well... hence the NPE.
