Problem with JAXBContext.newInstance

[Oliver Z.]

Thanks for the documentation link. It says, JPMS is supported when jaxb 
2.4.0 comes out. So in that case, this is simply not yet supported, is 
this correct? For the moment, i can remove the module-info.java, then it 
works - at least for the moment as workaround, until 2.4.0 is released.

I believe, the example below only works because it has no module-info.java
