GlassFish requires a JDK because it does not include one. One must utilize a JDK in order to start up GlassFish server.
It sounds like the Maven-based web application is starting up without issue because in this case GlassFish must be configured to start under a specified JDK 8 installation (not the one indicated within the NetBeans project). Therefore, the project is compiling under the specified JDK in NetBeans (in this case JDK11) and deploying the resulting WAR file without issue to the GlassFish server that is running under JDK 8. I just compiled a Maven WAR under JDK 12 in NetBeans and deployed to GlassFish 5.1 running on JDK 8. It seemed to work without issues.
