Github user StephanEwen commented on the issue:

I would suggest that we adopt the following pattern for all the places like
the one in this pull request where we catch Throwables:
```java
try {
...
} catch (Throwable t) {
ExceptionUtils.rethrowIfFatalErrorOrOOM(t);
// the other handling logic...
}
```
This requires to add the function `rethrowIfFatalErrorOrOOM(Throwable)` to
the `ExceptionUtils`, similar to the method here:
https://github.com/apache/flink/blob/master/flink-core/src/main/java/org/apache/flink/util/ExceptionUtils.java#L109
It would be even nicer if we could do something like Scala supports, but I
think there is no way better way to do this in Java than the way suggested above
```scala
try {
...
} catch {
case NonFatal(t) => // does not include OOM and internal errors
```
