📝 WalkthroughWalkthroughThe PR adds Java reload entry points, main-thread restart scheduling, runtime shutdown orchestration, and a native termination callback. It also updates timezone receiver registration to use a cached application context. ChangesApplication reload and runtime teardown

In `@test-app/app/src/main/java/com/tns/NativeScriptRuntime.java`:
- Around line 11-12: The NativeScriptRuntime.reloadApplication(String baseDir)
overload currently drops its baseDir argument, so callers cannot reload from a
chosen bundle location. Update this method to either pass baseDir through to a
new RuntimeHelper.reloadApplication(String baseDir) implementation that rebuilds
the runtime config from that directory, or remove the overload if it is not
meant to be supported; keep the API behavior aligned with the method signature
and related RuntimeHelper reload logic.
In `@test-app/app/src/main/java/com/tns/RuntimeHelper.java`:
- Around line 340-349: `registerTimezoneChangedListener` is unregistering
`timezoneChangedReceiver` with whatever `context` is passed in, but that can
differ between the initial call and `reloadApplication`, causing the old
receiver to remain registered. Update the listener bookkeeping so the same
Context instance used for registration is also used for `unregisterReceiver`
(for example by storing the registering Context alongside
`timezoneChangedReceiver` or consistently using `applicationContext` in
`registerTimezoneChangedListener` and its callers). Keep the existing
`IllegalArgumentException` handling only for truly stale registrations, and
ensure the old receiver is fully removed before assigning and registering the
new one.
In `@test-app/runtime/src/main/cpp/com_tns_Runtime.cpp`:
- Around line 358-362: The null-runtime checks in the affected callbacks do not
stop execution, so `runtime->GetIsolate()` can still be called on a null pointer
and crash. In each callback that resolves a `runtime` and then uses it
(`com_tns_Runtime` helpers around the reported branches), add an immediate
return inside the `if (runtime == nullptr)` path before any dereference, and
apply the same early-exit pattern consistently to all listed null-runtime
branches.
In `@test-app/runtime/src/main/java/com/tns/Runtime.java`:
- Around line 478-500: The termination flow in Runtime.destroyMainRuntime() and
terminateWorkers() is racing because the TerminateThread message is posted
asynchronously and workerIdToHandler is cleared immediately afterward. Add a
blocking handshake so terminateWorkers() waits until each worker has actually
processed the termination signal before destroyMainRuntime() continues with
runtimeCache.remove(), pendingWorkerMessages.clear(), currentRuntime.remove(),
and TerminateRuntimeCallback. Use the existing Runtime and workerHandler
messaging path to coordinate completion, and only clear workerIdToHandler after
all workers confirm shutdown.
