> There is a ThreadLocal bug that might be a source of problems for following code:
> here is a non trivial example that is broken,
> I'll try to make a trivial one that fails :)
> a simple page with test link
> <t:eventlink event="test">test</t:eventlink>
> page:
>     @Inject private HibernateSessionManager _sessionManager;
>     @Inject private ThreadCleanupHub _cleanupHub;
>     public void onTest(){
>         new Thread(new Runnable(){
>             public void run() {
>                 User user = (User) _sessionManager.getSession().load(User.class, Long.valueOf(1L));
>                 user.setName(user.getName()+"1");
>                 _cleanupHub.cleanup();
>             }
>         }).start();
>     }
> for java 1.5 this code fails to save data (threadCleanupHub looses listener list )
> and it works fo 1.6
> here's a link to articles about this bug
> http://crazybob.org/2006/07/hard-core-java-threadlocal.html
> and the bug
