Problem with Java 17

[lofidewanto]

Hi,

in this test class: https://github.com/gwtboot/gwt-boot-samples/blob/master/gwt-boot-sample-collection/src/test/java/com/github/gwtboot/sample/collection/client/ui/HelloWorldViewTest.java

... I'm using gwtmockito and with Java 11 everything works fine.

With Java 17 I get following error:
