There are indeed two possibilities for splash screens: (1) the Isabelle
one via "java -splash:..." and (2) the jEdit one via a special JWindow
(only when there is no -splash already).

I have now clarified and unified the situation as follows:

summary:     more uniform Isabelle splash screen -- avoid problems with

It means there should be always a regular java -splash:... and the jEdit
JWindow construction is always disabled.
