    API Changes

    • ➕ Added a generic result type R to ExecutionContext, Execution, AsyncExecution, and AsyncRunnable. This ensures that result types are unified across the API. It does mean that there are a few minor breaking changes to the API:
      • ContextualSupplier now has an additional result type parameter R. Normally this type is used as lambda parameters where the type is inferred, so most users should not be impacted. But any explicit generic declaration of this type will not compile until the new parameter is added.
      • PolicyExecutor, which is part of the SPI, now accepts an additional result type parameter R. This is only relevant for SPI users who are implementing their own Policies.
    • 🔄 Changed FailsafeExecutor.getAsyncExecution to accept AsyncRunnable instead of AsyncSupplier. This is a breaking change for any getAsyncExecution calls, but the fix is to simply remove any return statement. The reason for this change is that the provided object does not need to return a result since the result will already be passed asynchronously to one of the AsyncExecution complete or retry methods.
