-------------------------------------------------------------------
The NPE observed with JDK < 17 happens here:
https://github.com/openjdk/jdk11u-dev/blob/bcce7afba4503e3bc9f1d7dc2aa7de7eca86c764/src/jdk.javadoc/share/classes/jdk/javadoc/internal/tool/Start.java#L634C34-L634C47.
So {{doclet.getSupportedOptions()}} obviously returns {{null}}. According to
https://github.com/openjdk/jdk11u-dev/blob/bcce7afba4503e3bc9f1d7dc2aa7de7eca86c764/src/jdk.javadoc/share/classes/jdk/javadoc/doclet/Doclet.java#L86C27-L86C46
null must never be returned there.
