I am trying to disable the CheckForUpdates filter..
contributeRequestHandler(........
configuration.add("CheckForUpdates", new
CheckForUpdatesFilter(_updateListenerHub, checkInterval, updateTimeout),
"before:*");
.........
but I can't figure out how to override a filter through the
configuration object.. since you can't seem to be able to delete a
configuration entry, nor override it (with same name), and the filter
wasn't instantiated through as a service ( no decoration available ).
Any other thoughts??
I also tried to have our system change the checkInterval to be different
when production-mode=true, but then tapestry complained about a cyclic
loop..

The problem is certainly inside CheckForUpdatesFilter.
Application locks up, with all threads waiting for read lock inside

Project: Tapestry
Issue Type: Bug
Components: Framework
Affects Versions: 5.0.11, 5.0.12, 5.0.13
Environment: Red Hat, Tomcat, java version "1.5.0_10"
Reporter: Fernando
Assignee: Howard M. Lewis Ship
Priority: Critical
Attachments: js.txt, js2.txt
We are running in production, and pretty regularly the system seems to hang up.
After I do a jstack it looks like all the threads are tied up against some
lock.
Can you help me figure out the root cause?
I will be attaching the full jstack the the stuck threads all look like:
