I'm experiencing a memory leak due to orphaned threads in Tomcat. Particularly, it seems that Guice and the JDBC driver are not closing threads.

SEVERE: A web application appears to have started a thread named [com.google.inject.internal.util.$Finalizer] but has failed to stop it. This is very likely to create a memory leak.

SEVERE: A web application appears to have started a thread named [Abandoned connection cleanup thread] but has failed to stop it. This is very likely to create a memory leak.
I know this is similar to other questions (such as this one), but in my case, the answer of "don't worry about it" won't be sufficient, as it is causing problems for me. I have CI server which regularly updates this application, and after 6-10 reloads, the CI server will hang because Tomcat is out of memory.
I need to be able to clear up these orphaned threads so I can run my CI server more reliably. Any help would be appreciated!
