    [ https://issues.apache.org/jira/browse/GROOVY-10201?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17534286#comment-17534286 ] 

Paul King commented on GROOVY-10201:
------------------------------------

I cherry-picked part of those changes onto the GROOVY_3_0_X branch. Any chance you could check a snapshot version? I am assuming the bits I didn't bring across aren't critical to your problem.

Our JFrog snapshot repo for 3.0.x seems MIA again today. I have sent JFrog a message. When it's back up, I'll check that the snapshot was published successfully and then it would be great if you could try it out. I haven't included a simple reproducer test yet either.

> Doing early testing of some Groovy applications on Java 17 (ea31), and I'm encountering some exceptions like the following in unit tests. I'm testing on the 3.0.9 branch since 3.0.8 can't compile many of our Groovy classes against Java 17.
