Check your userlib for duplicate jar files.

Hi,
This problem did only occur from Modeler 7.9. and only if the IdP alias contained spaces. Without spaces the problem did not occur.
As this was not clear from the beginning we importted the LoginAddon module from the appstore, which contained duplicate jar files.
After all, by removing the LoginAddon from the project again and manually removing the jar files that were part of that module the Java errors disappeared.
