Bob Harner commented on TAP5-2588:
----------------------------------

Yes, help is always welcome. Right now I'm still trying to get all the unit tests to pass (much progress today). Are you able to build Tapestry and run the unit tests yourself?  https://tapestry.apache.org/building-tapestry-from-source.html

> You cannot use Tapestry with Java 9 because of an outdated ASM version in plastic (5.0.4). AFAICT, we'll need to upgrade to 6.0. My attempt do do so results in a {{ClassCastException}} in {{org.apache.tapestry5.plastic.ArrayAttributeAnnotations.explicit values for array attributes}}.
