[jira] [Commented] (KAFKA-2297) VerifiableProperties fails when
constructed with Properties with numeric values
[ https://issues.apache.org/jira/browse/KAFKA-2297?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14597942#comment-14597942 ]
Gwen Shapira commented on KAFKA-2297:
-------------------------------------
Yeah, I think its a known issue - VerifiableProperties only takes String values.
Considering that VerifiableProperties will be deprecated in next release in favor of AbstractConfig and ConfigDef, I'm not sure its worth fixing.
But if you already have a patch, feel free to submit :)
