Description

Had this exception come up a few times in different websocket tests. This stack trace is from WebSocketStatsTest.
This seems to occur very infrequently, have to run the test many times for this to have a chance of happening.

This is probably due to Issue #4971 and we likely missed a step on the websocket side related to that change.

I managed to reproduce this with some logging enabled.

Looks like the HttpReceiverOverHTTP read 0 bytes so released the network buffer, then after that another thread gets to the websocket upgrade in HttpReceiverOverHTTP.onUpgradeFrom() and there is a null network buffer because it was already released.

@lachlan-roberts this is a classic case where the HTTP response finishes before the HTTP request.

When the response completes, it nulls out HttpReceiverOverHTTP.networkBuffer, but it is only when the request also completes that HttpReceiverOverHTTP.onUpgradeFrom() is called (from the sender thread).

The simple fix is to add a null guard in onUpgradeFrom().
