[jira] [Created] (FLINK-2395) Check Scala catch blocks for
Throwable
Till Rohrmann created FLINK-2395:
------------------------------------
Summary: Check Scala catch blocks for Throwable
Key: FLINK-2395
URL: https://issues.apache.org/jira/browse/FLINK-2395
Project: Flink
Issue Type: Improvement
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.
