Problem with userCache using ehCache.

[nicholsl]

I'm in the process of integrating Acegi Security into a project I'm working on, and have come across a strange problem when running unit tests.

I have implemented my own authorizationDao, and setup a userCache to use the ehCache mechanism.

When I run the tests that call the authenticationDao.lookupByUsername() method, I get no problems. However, if I run other tests that do not use the lookupByUsername() method of the authenticationDao, I'm getting the following exception being thrown when the spring context(s) are closed:

09:43:07,437 XXX ERROR DefaultListableBeanFactory:1145 - destroy() on bean with name 'userCache' threw an exception

Im using ehCache 0.9, although it looks like Acegi uses ehCache 0.7 ? I'm setting the userCache to use the acegi ehCache mechanism in my spring context file:

<bean
id="userCache"
class="net.sf.acegisecurity.providers.dao.cache.EhCacheBa sedUserCache">
<property name="minutesToIdle">
<value>5</value>
</property>
</bean>


It looks like (and I may be wrong) that if nothing is put in the userCache, then there is a problem when the cache is destroyed.

Any pointers ?

Thanks

Apologies, I've just found the solution elsewhere in this forum (must bone up on my search skills).
