Hi all,
I'm working on an application with Jetty Continuations, and I'm
sometimes suffering from NoClassDefFoundError, where class not found
is a WhateverClass_FieldSerializer.
The context is a classical Continuations context, where users
connected to an application receive events from the server. In this
case, any user connected receives a notification when a new user
connects (so if 200 users are connected, 200 messages are sent).
In hosted mode, I sometimes get this exception in an already connected
session when a new user connects. Note that only one session receives
this message (I've never seen more than one connection receiving
theexception). No stack trace on the server, the problem only appears
client-side. No problem when running the compiled application (at
least, I've never seen it, even with more than 200 users connected).
So it's just a pain when in development mode ; this can happen even
with only 2 or 3 users connected.
Does anybody have any idea where this could come from ? Found nothing
on issues tracker.
Reproduced with GWT 1.5.3 and 1.6M
JDK 1.6.0_10
Win32
