Head commit for run: fdc2686e33d8dd1a338e3cc1432a6b8b2cad6d71 / Martijn Visser <[email protected]> [FLINK-39105][rest] Fix RestClientTest.testConnectionTimeout to handle environment-dependent exception types The test connects to 192.0.2.1 (RFC 5737 TEST-NET-1) with a 1ms connection timeout and asserts ConnectTimeoutException. On CI runners without a route to this address, the OS immediately returns "Network is unreachable" (AnnotatedSocketException) instead of timing out, causing the test to fail. Both ConnectTimeoutException and AnnotatedSocketException are SocketException subtypes, so the assertion now uses SocketException as the expected cause type. The existing hasMessageContaining(unroutableIp) check still verifies the failure is for the correct destination. Note: on environments where the OS rejects immediately, the configured connection timeout is never exercised. The test still verifies that connection failures propagate correctly, but does not validate the timeout code path on those environments. A more robust approach would require simulating a non-completing TCP handshake, which is not portable.
