Commit 670962 updated ServerWebSocketContainer such that contextToAddFilter can be set to null (from the handleAddingFilterMapping) method.

This can cause a NullPointerException later in the doUpgrade method since the following line doesn't guard for null:

WebSocketDeploymentInfo info = (WebSocketDeploymentInfo)contextToAddFilter.getAttribute(WebSocketDeploymentInfo.ATTRIBUTE_NAME);

Here's a complete stack trace:
