Description

DeltaSesssionManager executes a query to fetch all sessions for the current context shutting down and then serializes them to disk. There is no need to do this since the sessions are persisted in the session region on the servers.

This leads:

• to unaccounted for disk usage.
• execution of a potentially large query at shutdown.
• class casting executions in antlr in some Tomcat instances.
