[SNMP4J] ThreadPool in a J2EE environment

[Frank Fock]

Hi Brice,

 From my point of view a ThreadPool based on WorkerTask provided
by a JavaEE server does not make any sense. The server already
pools WorkerTasks and pooling it a second time does not
provide any benefit.

I am working on a package that provides helper classes to
integrate SNMP4J-Agent into a JavaEE server environment.

Best regards,
Frank
