With ~~UNDERTOW-1573~~, attributes are no longer cleared from requests and we have a leakage when going from Session to Request to request attributes.
Please, see attached image for an example of a stack.
We need to clear attributes after the listeners are invoked so we don't break the fix for ~~UNDERTOW-1573~~ while still preventing a memory leak.
