> Key: WELD-363
> URL: https://issues.jboss.org/browse/WELD-363
> Project: Weld
> Issue Type: Bug
> Components: Reflection layer
> Reporter: Shane Bryzak

> Weld is throwing the following NPE in Google App Engine - this is not happening on the first page render, rather on a refresh (Pete mentioned it is probably a serialization issue). If you delete the session cookie and refresh the page again the exception is not thrown.
