Are you using CAS or Logout (the latter shouldn't require that)? If not, any particular reason for using it? But I know Marvin certainly has been using it, obviously, so I doubt it leaks.

I don't use MySQL for storage but I use it for attribute resolution, and the driver I have doesn't leak. I've used the MySQL one for years but have switched to the mariadb driver more recently.

But I don't have any experience with the JPA storage option.

Plenty of people that aren't me are using it, so without it being an OpenJDK issue, I still doubt that's the problem.

Any sign of something causing the context in Tomcat be to redeployed while running? Tomcat leaks like a sieve, or used to, when that was done.
