--------------------------------
For Example:
I declared Callable implement like this:
public class CustomerCallback implements Callable<String> { ... }
Then, I used it in following step:
1,ExecutionCompletionService<String> execService = new
ExecutionCompletionService<String>(new ExecutionService(this.channel));
2,Class<CustomerCallback> clazz = CustomerCallback.class;
3,Constructor<CustomerCallback> cc = clazz.getConstructor(new Class[]{});
4,execService.submit(Executions.serializableCallable(cc, new Object[]{}));
In step 4, the IDE would tip me:
The method submit(Callable<String>) in the type
ExecutionCompletionService<String> is not applicable for the arguments
(Callable<capture#1-of ?>)

Key: JGRP-1688

Project: JGroups
Issue Type: Bug
Reporter: shen kim
Assignee: Bela Ban
Following this method:
static Callable<?> serializableCallable(Constructor<? extends Callable>
constructorToUse, java.lang.Object... args)
Assume one object extends Callable as MyCallable, so the symbol (\?) will replace with
MyCallable, and the result object Callable<MyCallable> maybe something wrong?
