greg frank commented on RF-7248:
--------------------------------

We are also seeing this bug frequently in production, any estimate on release 
date for 3.3.4?
The associated performance hit for enabling state serialization makes the 
workaround undesirable.

> Concurrent requests on a4j components causes infinite loop. While one request 
> is being proccessed by restoreChildState method, another request is senT for 
> proccessing. It causes the code to get stuck in hashmap.get() as the hashmap 
> is not synchronized and causes infinite loop.
