> Deflater.reset()  in activateObject  or passivateObject which reinitialize
> or unitialize the Deflater Object to be returned to or by the pool.
> I don't know why but it works like that !

> This solution implemented in TestDeflater works fine with Websphere 6.1 +
> IBM JVM and Tomcat 6 + Sun JVM.
> I have also tested this solution with orbeon 3.9. There is no more NPE due
> to Deflater.reset(). The application is launched and I can display each
