Description

Think I've only posted this in an old (90days+ hidden) Slack post where the discussion was to enable Liveview by default.

When you save a file during a restart or save multiple files at once it can happen that the restart will show these errors:

According to AI it's

The error occurs due to a race condition during LiveView's softRestart():
1. Normal flow: LiveView detects file changes → calls TiApplication.softRestart() 
2. Disposal phase (line 929): runtime.doDispose() synchronously disposes the V8 runtime, resetting all V8 handles (globalContext, moduleObject, etc.)
3. Transition window: Between doDispose() and initRuntime() (line 930), the V8 handles are invalid but the Java thread continues running
4. Race: A geolocation callback fires on the main thread during this window
5. Crash: The callback executes JS code → Ti.Locale.getString() → accesses Module._globalCtx.localeStrings → V8 "no access" error
The root cause is that nativeFireEvent in V8Object.cpp has no guard to check if the runtime is disposed/in transition.

Note: it's not just Ti.Locale.

Tried to fix it with AI but no solution yet. Maybe one other solution would be to queue the changes and not apply then until the app is fully ready again?

How to test it:
open a bigger project using liveview and save a file quickly.
