> I added a catch clause to startProcessing to catch the
RejectedExecutionException that can be thrown. Were you thinking of something
else?
What you did is needed, but I was thinking of something else. If the call
to `addMutations()` in the Runnable throws an unexpected exception, nothing
will be done about that exception. The batch writer should transition to an
error state. Thinking need to do something like the following.
```java
void queueMutations(final MutationSet mutationsToSend) {
queueThreadPool.submit(new Runnable() {
public void run() {
try{
addMutations(mutationsToSend);
} catch (Exception e){
updateUnknownErrors(e);
}
}
});
}
```
