Hi,
I am using **logstash 7.17.3** with Java 11 in containerized env.
Does this version of logstash also support **java 17**?
There is conflicting information from the two doc links from elastic - and hence the query for clarification -
1. As per [7.16.0 Release notes](https://www.elastic.co/guide/en/logstash/7.17/logstash-7-16-0.html#featured-7-16-0) , Logstash added tests against Java 17 and started supporting JDK 17 [#13330](https://github.com/elastic/logstash/pull/13330)
-\> This implies that versions \>= 7.16.0 support java 17.
2. But as per [7.17.details](https://www.elastic.co/guide/en/logstash/7.17/getting-started-with-logstash.html#ls-jvm) , logstash requires either of java 8,11 and 15.
I tried building logstash docker img with java17 installed - below error is seen -\>

**Pls let us know if java17 is supported on logstash 7.17.3, if yes, do we have to do additional steps to resolve the errors shared above?**
