Description

WebContextService sets the static context variables (which are ThreadLocals) to null during a call to destroy. For example requestContext.

In a classloading environment where the same WebContextService would be shared between webapps, this could lead to a NullPointerException in another application as the static variable has been set to null and that static would be shared.
