I'm open to better suggestions. Another option I considered was just removing the call to roomGraphics.dispose(); and letting GC take care of things. Alternatively, we could provide some form of global flag. I think I prefer the global flag that indicates that a shutdown is in process. I can think of several other places where such a flag would have been useful and we can expose it through a custom servlet context attribute such as "org.apache.tomcat.JVM_SHUTDOWN_IN_PROGRESS". I'll start looking at the global flag option. Meanwhile, any suggestions on how to improve the fix or an alternative fix welcome.
