Cannot start up server after applying a new patch


After installing a new fix pack / hotfix, the portal is not starting up, even though the temporary folders have been deleted.

For some reason there are duplicated jar files in the lpkg files that you can find in the marketplace folder. Please download a new vanilla bundle, install the desired fix pack / hotfix and replace osgi/marketplace folder in the corrupted bundle with the osgi/marketplace folder of the new instance.

Please make a backup first, in case a rollback will be needed - to avoid further issues.
