Extension Manager not accessible after upgrade to 6.2.14
If the Exension Manager is called with list view, it tries to find possible updates of each extension. Therefore for new available extension version the dependencies are tried to be resolved in comparison with the existing system. If an extension is checked, which is required from multiple other extensions, the dependencies might not meet the other requirements and an exception is thrown. Instead of breaking the EM, the exception should be caught and the update version should be checked.
Error occurs with following conditions:
- static_info_tables_de in version 2.0.3
- sr_language_menu in version 1.5.2
both required static_info_tables but if the updatable versions are checked, the extension dependencies don't match.
