Internal FQN removal

[girishadat]

I tried attaching a single string object to PojoCache and detached it later. But even after detaching the object from cache, when monitored through JConsole, I noticed the internal fqn is still there in the cache.

Why this reference is still maintained? When will it get removed?

Thanks,

For more clarity for my query,

# Content when cache is started

/ null

# Content when an object is attached to PojoCache [fqn is "/z/0"]

/ null
 /z null
 /0 {PojoCache.LOCK,PojoCache.PojoReference}
 /__JBossInternal__ null
 /0 null
 /__ID__ null
 /<some hash> {PojoCache.PojoInstance,PojoCache.Status}

# Content when the object is detached from PojoCache

/ null
 /z null
 /__JBossInternal__ null
 /0 null
 /__ID__ null

I am using PojoCache 3.0.0 GA (with CoreCache 3.0.3 GA).

My question is, why we have to maintain the third entry after detaching the object? Will it consume lots of memory when a large number of objects are attached and detached? Please advise.

Thanks in advance,

same problem with me

Please visit : https://community.jboss.org/message/3192 and https://jira.jboss.org/browse/PCACHE-85.

The work around is to call core cache APIs.

i.e. pojoCache.getCache().removeNode("fqn")

Hope this helps. Be careful @ making use of transactions directly.
