Thanks but the second part of the stacktrace is still on davmail. I need to investigate between these options: 1) make the binary package use java10 but this will require an upload when java11 is out 2) wrapper script to force the user to use java10 3) make it possible to compile davmail with target=1.8 and thus without --add-exports I'd be happy to get advice on this. I think I'll try 3) first. Alex
