Alfresco Solr 6.6.5 not start - Invalid version of java 11.0.9.1

[miroslav]

Hello,

I'm trying to install Alfresco Search services 2.0 on Debian GNU / Linux 10 (buster) with java Openjdk version "11.0.9.1" 2020-11-04. The service does not start and following error returns:

solr-8983-console.log

OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.
Invalid Java version 11.0.9.1

Usage: java -jar start.jar [options] [properties] [configs]
java -jar start.jar --help # for more information

What version of java should be used?

Thank you.

Java openjdk version "13.0.5" is running without problems.

This is a know problem for Jetty:

Every version including a "9" can't be used with SOLR 6.

Unfortunately, we can't fix that, so just avoid Java versions including a "9" (like 11.0.9.1)
