Problems with custom CachePolicy

[cenos]

I've created a mbean with my own version of TimedCachePolicy (that refreshes the expiration time when accessed from cache). I've put this jndi name into AuthenticationCacheJndiName (JaasSecurityManagerService) and it's been bound successfully.
My problem is when I call the getAuthenticationCachePrincipals method from JaasSecurityManagerService. It returns null because there is the code:
if( cache instanceof TimedCachePolicy )
{
TimedCachePolicy tcache = (TimedCachePolicy) cache;
validPrincipals = tcache.getValidKeys();
}
It means that you can bind your own CachePolicy, but it can't return the cached Principals, because TimedCachePolicy is hardcoded inside JaasSecurityManagerService mbean...

My solution was to create another version of JaasSecurityManagerService with my own TimedCachePolicy...

Am I doing something wrong? Any comments/suggestions/workarounds for this?

What version are you using? I can't find that specific snippet in 3.2.2 source base on JaasSecurityManager. It relies on specific implementation to only retrieve default timeout.

I'm using 3.2.1...

from JaasSecurityManagerService.java:
public List getAuthenticationCachePrincipals(String securityDomain)
{
CachePolicy cache = getCachePolicy(securityDomain);
List validPrincipals = null;
if( cache instanceof TimedCachePolicy )
{
TimedCachePolicy tcache = (TimedCachePolicy) cache;
validPrincipals = tcache.getValidKeys();
}
return validPrincipals;
}

I guess you're forced to extend and override TimedCachePolicy then, rather than implementing CachePolicy directly.

Thanks. I will try that... ;-)
