Bumps org.jetbrains.kotlinx:kotlinx-coroutines-core-jvm from 1.9.0 to 1.11.0.

Release notes

Sourced from org.jetbrains.kotlinx:kotlinx-coroutines-core-jvm's releases.

1.11.0

Various

  • Kotlin was updated to 2.2.20 (#4545).
  • Improved the published jar files (#3842, #4599).
  • Various documentation improvements, including complete rewrites of structured concurrency and error handling-related KDoc (#4433, #4596).

Breaking changes and deprecations

  • Moved Promise-related functions from JS and Wasm/JS to the new web target. On Wasm/JS, this is a breaking change. Before the change, Promise on Wasm/JS could work with arbitrary Kotlin types, but now, only JsAny subtypes are accepted (#4563).
  • Changed handling of coroutine exceptions that can't be propagated on JS and Wasm/JS. B efore, exceptions were logged, but now, they are reported to the JS runtime (#4451, #4631).
  • Deprecated using CoroutineDispatcher as the coroutine context key; now, ContinuationInterceptor has to be used instead (#4333).
  • Advanced the deprecation levels on kotlinx-coroutines-test APIs (#4604).
  • Added lint functions that mark passing a Job to coroutine builders as deprecated (#4435).

Bug fixes and improvements

  • Added a callsInPlace(EXACTLY_ONCE) contract to runBlocking in code shared between JVM and Native (#4368).
  • Added a callsInPlace(EXACTLY_ONCE) contract to suspendCancellableCoroutine (#4574).
  • Fixed flowOn incorrectly handling ThreadContextElement updates (#4403).
  • Fixed exceptions in user-supplied Thread.UncaughtExceptionHandler instances causing the internal coroutines machinery to fail (#4516).
  • Fixed CoroutineDispatcher.asScheduler in the RxJava integration not cancelling outstanding work when a Worker gets cancelled, which led to memory leaks in some scenarios (#4615).
  • Fixed SharedFlow entering an invalid state when a subscriber and an emitter are cancelled simultaneously (#4583).
  • Fixed an R8 optimization leading to shareIn/stateIn coroutines getting garbage-collected (#4646). Thanks, @​solevic!

Small additions

  • Added CompletableDeferred.asDeferred for obtaining a read-only Deferred view (#4408).
  • Added SharedFlow.asFlow for obtaining a Flow view with hidden hot flow semantics (#4530). Thanks, @​g000sha256!
  • Added a StateFlow.collectLatest overload returning Nothing to assist with finding unreachable code (#4454).
  • Added ReceiveChannel.consumeTo for consuming a ReceiveChannel into a MutableCollection (#4520).
  • Added a StateFlow<T>.onSubscription overload returning a StateFlow<T>, similar to SharedFlow<T>.onSubscription returning SharedFlow<T> (#4275). Thanks, @​xit0c!
  • Added terminal Flow operators for collecting a Flow to a Map (#1541).

Changelog relative to version 1.11.0

No changes, only the version is increased.

1.11.0-rc02

Restored binary compatibility with 1.10.2 and older versions on Wasm/JS for usages of Promise-related functions (#4661).

📝 Summary

Summary by CodeRabbit

  • Chores
    • Updated the coroutines library version used in Compose compiler builds and cross-version verification.

The Compose compiler classpath declarations for Compose variants and the cross-version verification matrix now use kotlinx-coroutines-core-jvm 1.11.0 instead of 1.9.0.

Suggested reviewers: krassx

Priority: ⬇️ Low

Change: Other

Merge Risk: 🟡 Moderate · up to 46a25

The dependency update makes the Kotlin 2.0.21 verification row fail and blocks the project’s check task. Use a compiler-compatible coroutines version for that matrix row before merging.

Architecture risk: 🔵 Low · up to 46a25

The change affects 1 system.

Maven Central kotlinx-coroutines-core-jvm 1.9.0 META-INF kotlin_module metadata version Kotlin 2.0.0

💡 Result:

**No—the available evidence does not establish that `kotlinx-coroutines-core-jvm:1.9.0` has `.kotlin_module` metadata version `2.0.0`.** Maven Central confirms the artifact and version, but its listing doesn’t expose the contents of the JAR’s metadata file. ([central.sonatype.com](https://central.sonatype.com/artifact/org.jetbrains.kotlinx/kotlinx-coroutines-core-jvm/1.9.0?utm_source=openai))

To verify the exact version, inspect the published JAR’s `META-INF/*.kotlin_module` file with a Kotlin metadata reader. Kotlin’s docs confirm module metadata is stored there, but the sources I found don’t show the value for this artifact. ([kotlinlang.org](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-metadata/?utm_source=openai))

Use a compiler-compatible coroutines version for each matrix row.

ComposeVariantMatrixTest expects the Kotlin 2.0.21 case to inject successfully. The shared 1.11.0 artifact contains Kotlin 2.2.0 module metadata, which Kotlin 2.0.21 can reject during compiler setup. The test then records Outcome.Failed, reports a matrix mismatch, and fails composeVariantMatrix, which is required by check.

The merge base used 1.9.0, whose metadata is accepted by Kotlin 2.0.21. Select the coroutines version per Kotlin row instead of using 1.11.0 for every compiler.
