I am wondering if this problem is related to the HTTP session timing
out. In the ROOT web application, we have the session time out set to
70 minutes:
WEB-INF/web.xml
> <session-config>
> <session-timeout>70</session-timeout>
> </session-config>
I received another ClassNotFoundException from the
EnvironmentClassLoader after 30 minutes, which is the default session
timeout for most Web apps.
