Answer 1

That seems to be the same problem as the previous report. Could be a problem with Webstart itself. I suggest trying to clear webstart's cache. To do that open start jcontrol (located in the bin directory of your Java installation directory). This should open a window with several tabs. On tab "General" should be section "Temporary Internet Files" with a button "Settings...". Clicking that button opens a dialog which lets you "Delete Files...". Alternatively, using the "View..." button next to "Settings..."  opens the cache viewer which can be used to delete specific files only.

Comments

Be careful to not use a local copy of the jnlp file. In that case the clearing of java web start cache won't be sufficient.

I have the same error when using yEd 3.10.2 and 3.11. I launch it with "java -jar /usr/share/yed/yed.jar". Java used is Oracle JDK 1.6.0_45
This error doen't occur with yEd 3.9.2 or older.

What else besides yed.jar is in your /usr/share/yed directory? I.e. what other directories, files, sym links, etc?

Thank you for pointing me in the right direction. The vectorgraphics.jar was not in the same directory. Now it works fine. Thank you

You are welcome. Glad you got it to work. Happy diagramming. :-)
