[jira] [Commented] (FLINK-10375) ExceptionInChainedStubException
hides wrapped exception in cause
[ https://issues.apache.org/jira/browse/FLINK-10375?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16621900#comment-16621900 ]

----------------------------------------
Noctune opened a new pull request #6719: [FLINK-10375] Add wrapped exception as cause in ExceptionInChainedStubException
URL: https://github.com/apache/flink/pull/6719
## What is the purpose of the change
ExceptionInChainedStubException does not have the wrapped exception as cause. This leads to generally bad exception traces like:
```
