Logstash error

[punithjigali (Punith C Jigali)]

Hi team, I have installed jdk 15.
I am getting this error when I run below command...

C:\Elastic stack\logstash-7.9.3\logstash-7.9.3\bin>logstash -f C:\Elastic stack\logstash.conf

Unrecognized VM option 'UseConcMarkSweepGC'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Thanks...

looking at the release notes of logstash - it seems JDK15 is not yet supported

https://www.elastic.co/guide/en/logstash/current/logstash-7-9-2.html - stated here that they work on support

https://www.elastic.co/guide/en/logstash/current/logstash-7-9-3.html - no mentioning that jdk15 is now supported
