Marc,
I'm not that familiar with how kars are supposed to work.
I'd need a small test case and instructions to replicate the issue.
I tried a few things, but could not replicate the problem in Kepler-2.2
I tried:
1. rm -rf ~/.kepler ~/KeplerData
2. Start Kepler-2.2 by clicking on the icon (I'm on the Mac)
3. Search for "Image", Drag an Image icon on to the canvas.
4. Double click and click on "Browse" for the source icon
5. Find an image outside of the Kepler tree. The image appears.
6. File -> Save and save it as Image.kar in MyWorkflows.
7. Double click on the icon, browse a new image
8. File -> Save As and save it as Image_1.kar
9. Exit Kepler
10. Restart Kepler-2.2
11. File -> Open and open Image.kar
12. File -> Open and open Image.kar
I've attached the two kar files.
If you can reproduce the error with something like the above, then I can
take a look.
I'm guessing that there is something up with how resources are being
found. In general, resources should be accessible
via the classpath.
I agree that the error messages you have are unusual, I'm not sure why
the name in the exception does not match up.
