There is nothing wrong with your code.  This log message is caused by  
a piece of code I added between beta-1 and beta-2 that clears a leaky  
cache in OpenJPA.

The problem we're running into is when we try to clear this cache in  
for an application using a tomcat class loader with this code:

     public static void cleanOpenJPACache(ClassLoader classLoader) {
         try {
             Class<?> pcRegistryClass =  
             Method deRegisterMethod =  
pcRegistryClass.getMethod("deRegister", ClassLoader.class);
             deRegisterMethod.invoke(null, classLoader);
         } catch (Throwable ignored) {
             // there is nothing a user could do about this anyway

We run into the following code in the Tomcat class loader when we load  
the PCRegistry class:

         // Log access to stopped classloader
         if (!started) {
             try {
                 throw new IllegalStateException();
             } catch (IllegalStateException e) {
name), e);

So, if the class loader is "stopped" it will log that huge message  
with stack trace for every class that we attempt to load.  It will  
take some experimenting to figure out how to avoid the exception  

Anyway, your code is fine, and I think the clean up code is working  
fine, but it would be nice to get rid of the annoying log message.
