Here's a self contained Maven project with a minimal (or at least
"reduced") reproducer for JDK-8261235:

https://github.com/eirbjo/jdk-8261235-reproducer

Here's the main method:

https://github.com/eirbjo/jdk-8261235-reproducer/blob/main/src/main/java/com/github/eirbjo/JDK8261235Reproducer.java

Tobias: This produces an instrumented class file with a lot less cruft than
the one I sent you so could possibly simplify analysis.

Thanks,
Eirik.
