That is a known [issue](https://github.com/logstash-plugins/logstash-filter-jdbc_static/issues/47#issuecomment-496606449). Read down to the end of the thread for additional issues.

The unrecognized VM option error suggests you are using a JRE that is [not supported](https://www.elastic.co/support/matrix#matrix_jvm).

OK fixed it.  
just incase putting it here incase someone came across same

in logstash conf dir, jvm.options file do this  
#-XX:+UseParNewGC ------\> comment this  
#-XX:+UseConcMarkSweepGC ------\> comment this  
-XX:+UseG1GC ----\> Add this line

copy your original jar file to logstash jar dir. or you can create a link there.

`# cp /usr/lib/oracle/12.2/client64/lib/ojdbc8.jar /usr/share/logstash/logstash-core/lib/jars/`

@Badger, I just upgraded java and elk stack

# java -version

java version "12.0.1" 2019-04-16  
Java(TM) SE Runtime Environment (build 12.0.1+12)  
Java HotSpot(TM) 64-Bit Server VM (build 12.0.1+12, mixed mode, sharing)

Do you think I got wrong java? But this was only problem with jdbc and everything else is working fine

Java 12 is not supported. That does not necessarily mean anything will fail.

ok. I guess will keep that java until it fails and  
use jdbc8 in to /usr/share/logstash/logstash-core/lib/jars dir to keep this going
