Jochen Kemnade created TAP5-2588:
------------------------------------
Summary: Does not work with Java 9
Key: TAP5-2588
URL: https://issues.apache.org/jira/browse/TAP5-2588
Project: Tapestry 5
Issue Type: Bug
Components: plastic
Affects Versions: 5.4.3
Reporter: Jochen Kemnade
Priority: Critical
You cannot use Tapestry with Java 9 because of an outdated ASM version in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}}.

The {{AbstractAnnotationBuilder}} tries to cast an {{int[]}} to an {{Object[]}}.
