the following code works perfectly fine in a Java 1.8 VM but produces a `LambdaConversionException` when executed in a Java 11 VM. Wheres the difference and why does it behave like this?

---
Code:
--

&lt;!-- language: lang-java --&gt;

    public void addSomeListener(Component comp){
        if(comp instanceof HasValue) {
            ((HasValue&lt;?,?&gt;) comp).addValueChangeListener(evt -&gt; {
                //do sth with evt
            });
        }
    }

[HasValue Javadoc][1]

Exception (V11 only):
--

&lt;!-- language: lang-none --&gt;

Workaround:
-

    ValueChangeListener&lt;ValueChangeEvent&lt;?&gt;&gt; listener = evt -&gt; {
        // do sth with evt
    };
    ((HasValue&lt;?,?&gt;) comp).addValueChangeListener(listener);
