title: Unable to run simple Java app with JRE 10
body: <p>Just tried to run my application in JRE 10 (since 9 got killed recently). The error below indicates that it requires ant.jar but this is a complete nonsense. The application <strong>doesn't need</strong> ant to run, and it works perfectly fine with all JRE's all the way back to 7. What am I missing? Why the runtime demands something which is totally irrelevant?</p>
