Solved: install JSesh 6.5.5.
Ok, this is the same as the previous bug, but I'm more precise now.
On windows, don't try to run JSesh with Java 8 installed now. Fetch a version of Java 1.7 instead. I willl find a solution when I have time.
Basically, Oracle modified the way of launching java programs, without telling anyone, and without checking it didn't break existing code.
A Very important warning : if you install with java8, and try to launch JSesh as usual, a window with "Open With" will open.
DON'T CHOOSE ANYTHING! CANCEL!.
So, if you try this:
and get this:
Don't choose any program. Cancel (either with the "cancel" button, or by clicking the red cross).
If you really want to use Java 8 (for instance, because you use another software which depends on it), then you can open the JSesh folder, go to the "libJSesh" folder, and select jseshAppli.jar. Create a shortcut to it. This shortcut will run ok (or, alternatively, you can double click on jseshAppli.jar).
You can move the shortcut, but not the original jar file.
The only thing is that the new shortcut sets a relatively low max memory for JSesh (which is usually not a problem, though).
