Incorrect @Async method signature
Reports incorrect return types of @Async methods.
For target method signatures, any parameter types are allowed. However, the return type should be either
void or Future. It is also possible to return the more specific ListenableFuture or CompletableFuture types, which allow for richer interaction with the asynchronous task and for immediate composition with further processing steps.
