Passing “-Dsolr.http1=true” did not help. So it’s impossible to start TLS-enabled Solr with Java 8.

The Linux startup script chooses the Jetty module "https8" instead of "https" when started with Java 8. This effectively disables HTTP2 with TLS. The same should happen on the Windows startup script.

The patch is easy, it's just an IF statement missing.
