Hi! I updated my ELK from version 6.2.3 to 6.3.0 and in 6.3.0 logstash-output-jdbc can't starts.  
In logsthash-plain. log i have next errors:  
[2018-06-21T17:16:00,948][ERROR][logstash.agent] Failed to execute action {:id=\>:main, :action\_type=\>LogStash::ConvergeResult::FailedAction, :message=\>"Could not execute action: PipelineAction::Create, action\_result: false", :backtrace=\>nil}  
[2018-06-21T17:16:01,047][ERROR][org.logstash.Logstash] java.lang.IllegalAccessError: tried to access class org.postgresql.Driver$ConnectThread from class org.postgresql.Driver

What is mean this erorr?  
Can anybody help? Or help to find another way to write data in postgresql?

This looks like a bug in 6.3.0 core. Please create an issue in [https://github.com/elastic/logstash/issues](https://github.com/elastic/logstash/issues)
