Support JDK 11.0.9.1

New Contributor

Although the documentation claims that CDH 6.3 supports JDK 11.0.3 or higher (https://docs.cloudera.com/documentation/enterprise/6/release-notes/topics/rg_java_requirements.html)... there seems to be a problem with the version numbering scheme used in JDK 11 (https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/Runtime.Version.html) not being supported by older versions of jetty that are still being used.

Dear @janvanbesien ,

Were you able to migrate to a supported version of JDK 11, please?

Kind regards,

Julius

Yes, we are currently stuck on 11.0.9 (rather than 11.0.9.1). But that is not really an acceptable solution in the longer term. We should be able to use the latest JDK 11 with all security patches etc, for current and future versions of the JDK.
