Description

When I try to add an oracle jdbc source connector in kafka-connect distributed mode via curl it will end up in a http 500 error.
To reproduce, feel free to clone my repo for that error: https://github.com/TranceMaster86/kafka-connect-oracle-error
In the readme I described how to reproduce the error.

It will hang up kafka-connect completely. All other connectors seems to stop working after I want to create an oracle jdbc source connector with a '@' in the connection string. I think this will be the main problem here. The oracle connection string looks like 'jdbc:oracle:thin:@hostname:port/service' or 'jdbc:oracle:thin:@hostname:port:SID'.
