Did anybody discover a workaround? The problem also occurs on graalvm-ce-java8-windows-amd64-19.3.0.

@nightscape, could you provide a stack trace of the error on JDK 8. I'm working on a fix, so it might be useful.

[nightscape]

@pejovica sorry, my bad. Something had gone wrong when switching from the JDK 11 to the JDK 8 version and I was apparently still using the JDK 11 version of native-image.
I ran the example from @znbang again with the JDK 8 version and it worked.

[pejovica]

Fixed in 123a027213cab3113b5a412304f105900f4f54a8.

@pejovica When do you expect 123a027 to be released?

[pejovica]

@mcred In GraalVM 20.0 early next year.

Why not in 19.3.1 ?
