Description of the issue:
using thread pool in AOP: fixedPool.submit
there is weird that fixedPool.submit called a lots times



Steps to reproduce:
let:

final ExecutorService fixedPool = Executors.newFixedThreadPool(10);

@AsyncDBCall
public void ssss(){
	System.out.println("ssss");
}

when calling:

@Test
public void aa2222(){
	instance.ssss();
}
    

if I wrote a interceptor (1) or (2), I got:
AsyncDBCall1
AsyncDBCall2
AsyncDBCall1
AsyncDBCall2
AsyncDBCall1
AsyncDBCall2
AsyncDBCall1
AsyncDBCall2
AsyncDBCall1
...
AsyncDBCall2
AsyncDBCall1
AsyncDBCall2
AsyncDBCall1
AsyncDBCall2
AsyncDBCall1
AsyncDBCall2

(1)         bindInterceptor(Matchers.any(), Matchers.annotatedWith(AsyncDBCall.class), new MethodInterceptor() {
            @Override
            public Object invoke(final MethodInvocation invocation) throws Throwable {
                System.out.println("AsyncDBCall1");
                return fixedPool.submit(new Callable<Object>() {
                    @Override
                    public Object call() throws Exception {
                        try {
                            System.out.println("AsyncDBCall2");
                            return invocation.proceed();
                        } catch (Throwable throwable) {
                            throw Throwables.propagate(throwable);
                        }
                    }
                });
            }
        });


(2) bindInterceptor(Matchers.any(), Matchers.annotatedWith(AsyncDBCall.class), new MethodInterceptor() {
	@Override
	public Object invoke(final MethodInvocation invocation) throws Throwable {
		System.out.println("AsyncDBCall1");
		fixedPool.submit(new Runnable() {
			@Override
			public void run() {
				try {
					System.out.println("AsyncDBCall2");
					invocation.proceed();
				} catch (Throwable throwable) {
					throw Throwables.propagate(throwable);
				}
			}
		});
		return null;
	}
});
