Having strange behavior when running tests. Maven 3.6.3 with Java 8 tests run fine, but when trying Java 11 get the below error when trying to execute the following code:

    public void testUpdateAlignment()
    {
        ImageConfig imageConfig = new ImageConfig();
        imageConfig.setAlignment(ImageAlignment.TOP);

        ImageElement image = Document.get().createImageElement();
        // Apply left alignment.
        image.getStyle().setFloat(com.google.gwt.dom.client.Style.Float.LEFT);
        // Update the alignment.
        imageConfigDOMWriter.write(imageConfig, image);

        assertEquals(ImageAlignment.TOP, imageConfigDOMReader.read(image).getAlignment());
        assertTrue(StringUtils.isEmpty(image.getStyle().getProperty(Style.FLOAT.getJSName())));
    }

Error:

Did Java 11 change the way enums are accessed, or am I missing something here? Wasn't able to find similar issues any where else. Thank you!

    jdk-11 did introduce nest-mates, yes, but the fact that you get a `IncompatibleClassChangeError` might mean a simpler thing here. do you do `mvn clean` before running your tests? – Eugene Jul 26 '21 at 17:03
  • Yes the command that I run every time is `mvn clean install` followed by the flag arguments. – tunnelvisions Jul 27 '21 at 14:56
  • What version of `gwt` are you using? is it compatible with Java-11? You might have to upgrade. – Naman Jul 27 '21 at 15:11
  • Great question, yes I'm using [gwt 2.9](http://www.gwtproject.org/release-notes.html#Release_Notes_2_9_0) which is compatible with Java 11. – tunnelvisions Jul 27 '21 at 15:55
