1872429 - GeckoRuntime.onShutdown should propagate the exception cause information

Status: NEW

(GeckoView :: General, task, P2)

Description

[Jonathan Almeida [:jonalmeida]]

When GeckoRuntime.Delegate.onShutdown is called we throw an exception because we get into a broken state with the engine that will put the users into a worse state if we don't crash.

However, the crash information we get from that is unhelpful and does not include the source or reason for the GeckoRuntime shutdown so that we have a better idea of what cause that particular shutdown.

This should be looked at for prioritization to help stacks such as bug 1889652 have more information. Ideally, we need to get what Gecko exception or thread issue happened to get us into this state.

Relevant code:

• Where the Gecko thread exits at
• Where the exit event is sent
• AC onShutdown starting

Previous metadata change:

• Bug 1708580 - Add metadata for onShutdown
• Issue 10073 - some discussion on the issue
• Was a similar meta at one point - bug 1771978

Unsetting severity to put this into triage queue.
