STS allows to bypass any checked exceptions

[Attila Kelemen]

Also, another issue is that, if I shutdown the STS, then every
exception happening will be silently discarded with no means to see
them. Even though the action can have bugs in case of shutdown. For
example, it can run into an NPE or whatever in a mismanaged cleanup.
This is, because currently STS does this while running the task:

```
T result = null;
Throwable ex = null;
try {
    result = task.call();
} catch (Throwable e) {
    ex = e;
}

// invoke handleComplete if the scope has not shutdown
if (!scope.isShutdown()) {
    // ... omitted handleComplete logic
}
```
