Port to java 11 (LTS)

Before starting that, we must wait for geotools to do their part: https://github.com/geotools/geotools/wiki/Java-9-Compatibility

Maybe Jasper Reports has trouble too.

GeoTools 11 should work, as of 21.0.

Jasper Reports not.

Geoserver 2.15.0 (and Geotools) are running fine with Tomcat9 and java-11-openjdk-amd64

I've tried to run MapFish print-servlet-3.19.0.war on the same Tomcat9 instance, running java-11-openjdk-amd64 and MapFish fails with:

22-Apr-2019 09:30:07.035 INFO [report subreports #1] org.apache.catalina.loader.WebappClassLoaderBase.checkStateForResourceLoading Illegal access: this web application instance has been stopped already. Could not load [com.sun.media.imageio.stream.RawImageInputStream]. The following stack trace is thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access.

Yep, still waiting for support in Jasper Reports...

Seems that Jasper Reports works with 11 now: https://github.com/TIBCOSoftware/jasperreports/issues/43
