Subject Re: Groovy with JDK 16
Date Tue, 15 Jun 2021 02:35:18 GMT
Hi Graeme,

> is there an issue report to track this or should I file one?

The issue reports were created, and I've already fixed the dynamic proxy related issues in
the PR[1].
https://issues.apache.org/jira/browse/GROOVY-10137
https://issues.apache.org/jira/browse/GROOVY-10138

Other issues were found when running on JDK16 too, see http://groovy.329449.n5.nabble.com/Groovy-Dev-f372993.html

P.S. sorry for the late reply. I'm too busy recently to look into issues...
