> One part of the parent issue is the SFSB cache is stopped before other elements of the container. This leads to undeployment problems like the following:

> Basically, the cache is stopped so it's nulled out some fields, but the the container stops its pool, which calls remove() on beans, thus invoking on the cache.
> Note that fixing this doesn't completely fix the parent issue; still need to prevent shutdown of the container while still handling requests and ensure that requests that come in while shutdown is happening get an exception that triggers failover in a clustered proxy.
