Yes, you need locks on reads: if isolation level

I just tracked this in the code - there seems to be no bug in this area.
Threadsafe access to the keyset is garanteed by a ReadLock on the Node.
The Concurrentmodificationexception should only be thrown, if
'getChildrenNames()' and the iteration over the keySet are not done within the

I finally figured out how to resolve this problem once and for all. In my last
posting, I mentioned that deleting the JBoss server directory and replacing it
with a fresh copy worked for me. I reproduced the problem on anther PC and was
able to understand exactly how to resolve this issue.

So are filters implemented as eviction policies in JBossCache ?
I'm thinking where code like this would go, e.g. would the taglibs, cache

Since my original posting was truncated, here comes the rest:
it executes the n.createChild(...) but never calls the CacheLoader to get the

So I've committed the intial version of the POJO container.
It is still a prototype (with some horrible hacky code in parts) but it does
the job
for the initial M1 release.
You can now configure a set of *single* set interceptors for a POJO
and it will put a proxy container in front of it.
The key feature is that you don't need to add dependencies to the bean itself.
You can define the dependencies on the interceptor.
When we have true aspects, you will be able to automagically get dependencies.
e.g. If you add the transaction demarcation aspect it will *know* it needs to
wait
So the container construction code is a bit hacky.
I'm actually thinking that this config should be more long winded and more
explicit but giving you more control.
i.e. you construct the whole container using the metadata.
In more detail, currently we have the implicit container when you

I'm probably going to make all methods of Node package-private, b/c it doesnt
make sense to expose Node to users anymore. Reason: we need to go through the
interceptor stack, e.g. for locking, replication, cache loading etc, and if
someone accesses a Node directly, they will bypass the stack.
