Till Rohrmann commented on FLINK-2395:
--------------------------------------
I think this issue can be closed since we are removing the Scala components
anyway quite soon.
> Check Scala catch blocks for Throwable
> --------------------------------------
>
> Key: FLINK-2395
> URL: https://issues.apache.org/jira/browse/FLINK-2395
> Project: Flink
> Issue Type: Improvement
> Components: Build System, Scala API
> Reporter: Till Rohrmann
> Priority: Minor
>
> As described in [1], it's not a good practice to catch {{Throwables}} in
> Scala catch blocks because Scala uses some special exceptions for the control
> flow. Therefore we should check whether we can restrict ourselves to only
> catching subtypes of {{Throwable}}, such as {{Exception}}, instead.
