  • KTOR-9788 Netty: engine double-responds after its built-in 400, crashing the call-handler coroutine with "Headers can no longer be set because response was already completed"
  • KTOR-9834 HttpClient eagerly initializes SLF4J during Android startup
  • KTOR-9701 Jackson/Gson converters waste time on unnecessary Dispatchers.IO dispatch

Thanks for the bump — holding off on this one for now, since there's a blocking inline finding to sort out before it can merge.

Blocking: Ktor 3.6.0 breaks SSE streaming under testApplication.

Problem — In 3.6.0 the test host no longer hands the response to the client until the response body completes. An MCP SSE stream never completes by design, so prepareGet(...).execute { } against an SSE endpoint blocks forever instead of entering the lambda. The regression is confined to ktor-server-test-host; real engines are unaffected, so this is a test-harness break rather than an SDK defect.

Failure scenario — 8 of 228 :kotlin-sdk-server:jvmTest tests hang for 60s and fail with UncompletedCoroutinesError: KtorRouteExtensionsTest (×3), StreamableHttpServerTransportTest (×3), KtorApplicationExtensionsTest, SseServerTransportTest. That is exactly what Build (Linux Tests) is currently red on. Reproduced locally with the version as the only variable: the same 8 fail on 3.6.0, all 228 pass on 3.5.2. Reduced further — a testApplication that installs SSE + mcp() and calls client.prepareGet("/").execute { } never enters the lambda on 3.6.0 (60s timeout), while on 3.5.2 it reads the endpoint event and finishes in ~3s.

Suggested fix — Hold at 3.5.2 and report upstream; the likely culprit is KTOR-8705 / ktorio/ktor#5868, which changed the channel writer's coroutine context in TestApplicationResponse. Let Dependabot retry once a 3.6.x carries the fix. Taking 3.6.0 now would instead require porting the SSE tests off testApplication onto a real embeddedServer(CIO) on an ephemeral port — a change too large to ride along in a dependency bump.
