Just for the reference, the error goes away after relevant annotations are added - private static final Function1<ResultSet, Function0<Object>> AUTO_ROW_BUILDER_FACTORY =

This also causes issues with ASM (used by forbiddenapis), see policeman-tools/forbidden-apis#173 Javac creates a bad class file when you use type annotations inside a try...catch, that causes many third party tools to fail. |
