In `@app/src/main/java/com/itsaky/androidide/actions/build/DebugAction.kt`:
- Around line 85-90: preExec calls showDebuggerNotReadyMessage(...) directly on
a potential background thread; wrap that call in
withContext(Dispatchers.Main.immediate) so the AlertDialog is created/shown on
the main thread. Locate the javaLsp check around
ILanguageServerRegistry.default.getServer(JavaLanguageServer.SERVER_ID) in
preExec and replace the direct showDebuggerNotReadyMessage(activity) invocation
with a withContext(Dispatchers.Main.immediate) {
showDebuggerNotReadyMessage(activity) } block to match the other dialog paths.
In
`@app/src/main/java/com/itsaky/androidide/activities/editor/ProjectHandlerActivity.kt`:
- Around line 973-979: The current catch in the debug-client handshake is too
broad (catching Throwable) and will swallow coroutine cancellations; change the
handler in the connectDebugClient(...) call so it only catches Exception, but
explicitly rethrow CancellationException if encountered (i.e., if (e is
CancellationException) throw e), then perform Sentry.captureException and
logger.error and return listOf(DebugClientConnectionResult.Failure(cause = e))
for other exceptions; update the try/catch around
connectDebugClient(debuggerViewModel.debugClient).values accordingly to use
Exception and rethrow CancellationException.
In
`@lsp/api/src/main/java/com/itsaky/androidide/lsp/api/DefaultLanguageServerRegistry.kt`:
- Around line 125-130: The current write-lock block in
DefaultLanguageServerRegistry wrongly restores the old instance after inserting
the new one: the mRegister.put(server.serverId, server) result (old) is
immediately put back, preventing updates; fix by deciding intended behavior and
implementing it—either detect duplicate server.serverId and throw/return early
(e.g., check mRegister.containsKey(server.serverId) and fail fast) or keep the
new instance and remove/retire the old (remove the mRegister[old.serverId] = old
line so the new server remains and perform any retirement/cleanup on old).
Ensure changes touch the lock.writeLock() block that uses
mRegister.put(server.serverId, server) and the local variable old.
- Around line 136-140: The unregister(serverId: String) method currently removes
the server from mRegister and throws if absent but never calls shutdown() on the
removed instance; change it to acquire the write lock, remove the entry from
mRegister, if the removed value is null simply return (do not throw), release
the lock, and then call shutdown() on the removed server instance outside the
lock to avoid holding the lock during shutdown; ensure the logic references
unregister, mRegister, and shutdown() so the removed server is shut down after
removal.
- Around line 63-72: In DefaultLanguageServerRegistry.kt, in the block where you
call server.connectDebugClient(client) (which currently catches Throwable and
maps everything to DebugClientConnectionResult.Failure), change the error
handling to re-throw CancellationException immediately so coroutine cancellation
is preserved, and replace the broad catch(Throwable) with catches for the
concrete exceptions that connectDebugClient() can actually throw (log via
sLogger.error and convert those specific exceptions to
DebugClientConnectionResult.Failure); ensure you still log the server.serverId
and the exception when returning Failure but never swallow or convert
CancellationException.
- Around line 55-77: The method connectDebugClient currently holds
lock.readLock() across suspend calls (server.connectDebugClient), blocking
writers; instead, while holding lock.readLock() copy/snapshot the registry
entries (mRegister.values) into a local list and then release the read lock
before iterating and calling the suspend function
server.connectDebugClient(client); build the result map from that snapshot and
preserve the existing error handling (sLogger.error and mapping to
DebugClientConnectionResult.Failure) while ensuring lock.readLock().unlock()
happens immediately after taking the snapshot.
- Around line 111-117: In DefaultLanguageServerRegistry::onProjectInitialized,
acquire the registry read lock before reading mRegister to avoid races with
register()/unregister(); wrap the iteration over mRegister.values and the calls
to server.setupWithProject(project) inside lock.readLock() (or use the
readLock().lock()/unlock() pattern or a try/finally) so access is consistent
with other methods that guard mRegister.
In `@lsp/api/src/main/java/com/itsaky/androidide/lsp/api/ILanguageServer.kt`:
- Line 83: The default implementation of connectDebugClient currently always
returns DebugClientConnectionResult.Success causing false positives; change it
so the method delegates to debugAdapter?.connectDebugClient(client) and return
that result when debugAdapter is non-null, otherwise return an explicit failure
(e.g., DebugClientConnectionResult.Failure or a suitable error variant) so
callers see unsupported/uninitialized debug adapter; update the suspend fun
connectDebugClient(client: IDebugClient): DebugClientConnectionResult to perform
this delegation and null-check.
In
`@lsp/api/src/main/java/com/itsaky/androidide/lsp/api/ILanguageServerRegistry.kt`:
- Around line 71-81: The singleton getter for ILanguageServerRegistry (sRegistry
/ default) is not thread-safe; replace the nullable backing var and manual
check-then-set with a synchronized lazy initialization: remove sRegistry, make
default a val initialized via Kotlin's lazy with thread-safety (e.g., val
default: ILanguageServerRegistry by lazy(LazyThreadSafetyMode.SYNCHRONIZED) {
DefaultLanguageServerRegistry() }) so DefaultLanguageServerRegistry is created
once safely across threads.
In
`@lsp/java/src/main/java/com/itsaky/androidide/lsp/java/debug/JavaDebugAdapter.kt`:
- Around line 627-630: The recovery path in run() that calls
listenerState.startListening() when listenerState.isListening is false can
reopen the socket after a prior close(); before attempting to restart, check the
adapter's shutdown/interrupted state (e.g., a shutdownRequested flag or
Thread.currentThread().isInterrupted()) and skip the self-heal if shutdown was
requested, or alternatively remove the self-heal logic entirely; update the
block around listenerState.isListening and startListening() so it first
returns/exits the loop when a shutdown/interruption is observed, otherwise
proceed to call startListening().
- Around line 154-163: The current catch in the withContext block catches
Throwable and therefore swallows coroutine cancellation; change the error
handling around listenerState.startListening() so CancellationException is not
absorbed: add "import kotlinx.coroutines.CancellationException", narrow the
catch from Throwable to Exception (or explicitly catch Exception), and if you
must catch Throwable ensure you rethrow CancellationException (i.e., if (e is
CancellationException) throw e) before logging/returning the Failure; update the
block around listenerState.startListening() and the catch that currently logs
"Failed to listen for incoming JDWP connections" to follow this pattern.

- Around line 83-84: Make the EventBus subscription lifecycle idempotent and
thread-safe by (1) guarding EventBus.getDefault().unregister(this) inside
destroy() with EventBus.getDefault().isRegistered(this) so unregister is only
called when subscribed, and (2) moving the isRegistered() check currently in
register() into the same write-lock critical section where the registry map is
updated so registration and the map update occur atomically; update the
register() method to acquire the write lock, check isRegistered(), then call
register(this) and update the map only if not already registered.
In
`@lsp/java/src/main/java/com/itsaky/androidide/lsp/java/debug/JavaDebugAdapter.kt`:
- Around line 148-178: Currently you reassign _listenerState before tearing down
the previous JDWPListenerThread which can cause the new client to be used when
the old thread accepts a connection; fix by first stopping/interrupting/joining
the existing listenerThread (reference listenerThread and JDWPListenerThread)
and only after it has terminated assign the new _listenerState =
ListenerState(...) and start a new JDWPListenerThread, or alternatively change
the accept callback (onConnectedToVm) to receive the accepted ListenerState
instance instead of reading the mutable _listenerState field so the accepted
connection uses the correct ListenerState/client.
