<T> T newProxy(T target, Class<T> interfaceType, long timeoutDuration, TimeUnit timeoutUnit)
interfaceType that delegates all method calls to the target object, enforcing the specified time limit on each call. This time-limited delegation
is also performed for calls to Object.equals(java.lang.Object), Object.hashCode(), and Object.toString().
If the target method call finishes before the limit is reached, the return value or
exception is propagated to the caller exactly as-is. If, on the other hand, the time limit is
reached, the proxy will attempt to abort the call to the target, and will throw an UncheckedTimeoutException to the caller.
It is important to note that the primary purpose of the proxy object is to return control to the caller when the timeout elapses; aborting the target method call is of secondary concern. The particular nature and strength of the guarantees made by the proxy is implementation-dependent. However, it is important that each of the methods on the target object behaves appropriately when its thread is interrupted.
For example, to return the value of target.someMethod(), but substitute DEFAULT_VALUE if this method call takes over 50 ms, you can use this code:
TimeLimiter limiter = . . .;
TargetType proxy = limiter.newProxy(
target, TargetType.class, 50, TimeUnit.MILLISECONDS);
try {
return proxy.someMethod();
} catch (UncheckedTimeoutException e) {
return DEFAULT_VALUE;
}

The difference with callWithTimeout(Callable, long, TimeUnit) is that this method
will ignore interrupts on the current thread.
