Was having the same problem which seems to have been given an easy workaround in the meantime, here:
Basic solution is to create (or edit if you already have one) your launcher.bat or command to include, at minimum, "java -jre [yourserver.jar]". For example, I've got a launcher.bat that is only the following:
java -jar minecraft_server_16w04a.jar
and the error is now going.
Hope it helps and good luck!
