Mats Andersson commented on TAP5-2588:
--------------------------------------
I stepped into a couple of issues related to ASM and Java 9. In
org.apache.tapestry5.internal.plastic.asm.ClassVisitor#visitNestMember ASM7 is
required, but calls from internal/plastic and ioc modules are made using ASM4
as parameter. See patch below for details:

> Key: TAP5-2588

> Project: Tapestry 5
> Issue Type: Bug
> Components: plastic
> Affects Versions: 5.4.3
> Reporter: Jochen Kemnade
> Assignee: Thiago H. de Paula Figueiredo
> Priority: Critical
> Fix For: 5.5.0

> Attachments:

>
> You cannot use Tapestry with Java 9 because of an outdated ASM version in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

> array attributes}}.
