1. Well yes of course the issue is the synchronized HashTable :)

2. It's deep inside JBoss AS code, in the JNDI server implementation.  
Ideally we would not call it a thousand times per request.

ManagedEntityIdentityInterceptor - which is responsible for the  
HashTable calls.

4. There might be other hotspots of thread contention in a typical  
Seam request.
