The upgrade introduces support for a wide range of JDK versions (from 8 to 15, the latest version supported by NetBeans 12.3), and the switch from Ant to Maven makes the IGV build simpler, faster (first-time build is approximately 5x faster), and more stable (all dependencies are fetched directly from the Maven central repository).

Thank you for modernizing IGV. I manage to import this project to IntelliJ. The process is hassle-free!

I also ran using jdk8/jdk11 on macOS. I haven't identified any problem so far.

src/utils/IdealGraphVisualizer/Filter/pom.xml line 93:

Does this mean that module `Filter` will depend on external nashorn after jdk15? 

I know that jdk doesn't remove nashorn util jdk15, but does it make sense that IGV always picks up external nashorn. My concern is "javascript" in jdk8/11 may be not well-maintained and leave vulnerability behind.
