scudellari opened a new pull request #17227: URL: https://github.com/apache/flink/pull/17227
## What is the purpose of the change When running on JDK11 [JDK-8237858](https://bugs.openjdk.java.net/browse/JDK-8237858) can cause SocketTimeoutExceptions to be thrown during ServerSocket.accept() calls, even when configured with an infinite timeout. This change works around this issue by catching these erroneous exceptions and retrying indefinitely. ## Brief change log - Added `acceptWithoutTimeout` method to `NetUtils` that calls `ServerSocket.accept()` and suppresses `SocketTimeoutException`s. Added a unit test to cover the new method. - Migrated all `ServerSocket.accept()` calls to use `acceptWithoutTimeout`, with exception to the `EchoServer` test as it sets an explicit timeout. ## Verifying this change This change added tests and can be verified as follows: - Added unit test to verify `acceptWithoutTimeout` suppresses `SocketTimeoutException`s. - Most migrations touched unit tests directly. I have run those to verify they still pass. ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): **no** - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: **no** - The serializers: **no** - The runtime per-record code paths (performance sensitive): **no** - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn, ZooKeeper: **yes - blob server** - The S3 file system connector: **no** ## Documentation - Does this pull request introduce a new feature? **no** - If yes, how is the feature documented? **not applicable** -- This is an automated message from the Apache Git Service.
