> Key: FLINK-10234
> URL: https://issues.apache.org/jira/browse/FLINK-10234
> Project: Flink
> Issue Type: Sub-task
> Components: Core
> Affects Versions: 1.7.0
> Reporter: Chesnay Schepler
> Assignee: Chesnay Schepler
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.7.0

>
> In {{FutureUtils}} the following code doesn't compile with java 9:
> {code}
> ... = scheduledExecutor.schedule(
> () -> retryOperationWithDelay(resultFuture, operation, retries - 1, retryDelay,
> ...,
> ...,
> ...);
> {code}
> The reason is that the compiler cannot determine whether the lambda should be a {{Runnable}} or a {{Callable<V>}}, resulting in incompatible bounds for the return type.
