Thanks.  I will look at this and fix/patch in the current Trunk by early next

BridgeImpl incorrectly cleans up after exceptions; retains contexts
-------------------------------------------------------------------

                Key: PORTLETBRIDGE-214
                URL: https://issues.apache.org/jira/browse/PORTLETBRIDGE-214
            Project: MyFaces Portlet Bridge
         Issue Type: Bug
         Components: Impl
   Affects Versions: 2.0.0
           Reporter: Scott Oaks
           Assignee: Michael Freedman
        Attachments: stack.txt


The exception handling of BridgeImpl.doFacesRequest() is incorrect, which leads 
to contexts not being released after an exception.
When an exception is thrown to the doFacesRequest() method, it ends up in this 
code:
try {
    ...
} catch (Exception e) {
   ...
   context.getExternalContext().log("Exception thrown in 
doFacesRequest:resource", e);   // line 1168
  ...
} finally {
  ...
  context.release();
  ...
}
The first problem is that whatever error is getting thrown to us is lost 
because line 1168 is generated a NullPointerException from 
context.getExternalContext().log(). So that NPE gets thrown from the exception 
block and the original, actual root-cause, exception is lost.
The reason that this code fails is that context.getExternalContext() returns null -- the processing has been redirected, and this context has already been released in redirectRender(). Which leads to the much more serious issue -- the new context established by redirectRender() is never released in the exception handling: the context.release() call in the finally block of doFacesRequest() is the original, already released context.
