+Currently, I must use Java &lt; 15 to build plugins. 
 It would be nice if more modern JDKs were supported by our build.xml scripts. 

 Java 15 has removed Nashorn, you must provide an engine for running JavaScript yourself. GraalVM JavaScript currently is the preferred option.

The main issue is this:
Java 15 has removed Nashorn, you must provide an engine for running JavaScript yourself. GraalVM JavaScript currently is the preferred option.

openjdk 15 also works, but it disappeared from ubuntu repos (tar.gz available via https://github.com/AdoptOpenJDK/openjdk15-binaries)

It would be nice to bump the version dependency to Java 21 (latest LTS) or Java 17 (previous LTS).

Regarding availability in major Linux distros:
- both are available with RHEL 8 onwards
- both are available on Ubuntu Focal Fossa (20.04) onwards
- 21 is not available on Debian stable
- both are available as community packages on SEL
