JDK Release Cadence

Hello,
I am currently looking into what the new release cadence for the JDK means for Tomcat.
-Is there a plan for tomcat to support Oracles new release cadence, i.e. supporting all versions of the JDK or only the LTS  versions?
-Which JDK are supported by Tomcat? Like  Oracle JDK (Free),  Oracle JDK (Commercial), AdoptOpenJDK, Zulu Enterprise
If this is not the right place to ask these questions please point me in the right direction.

Thanks,
Johannes

Tomcat has a (spec mandated) minimum Java version.

To date we have supported Tomcat on any JVM that a) meets the minimum version requirement and b) passes the Java TCK irrespective of vendor.

So far, the change in release cadence hasn't changed that. I also don't see anything that would change that.

The latest Tomcat 7 8 and 9 releases all work on Java 10 and with the 11 EA release. Now the first 12 EA release is out we'll be testing that too.

If someone finds and reports a Java version related bug I my expectation is that it will be fixed. Almost certainly for the next release.

HTH,

Mark
