Share results in 500 after CORS & CORS Filter enabled exactly

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

Using Alfresco ECM Community 2017.2 on macOS Server, enabling CORS and CORS Filter breaks Alfresco Share Functionality in Web Browser (any Document Action results in Error 500), but CORS API Authentification and AOS / Webservices works well. 

The Only changes I have altered is following:

added following JAR Files, according to Alfresco Documentation:

cors-filter-1.9.3.jar

java-property-utils-1.9.1.jar

to: ../tomcat/webapps/alfresco/WEB-INF/lib

Uncommented CORS Sections:

on ../tomcat/webapps/alfresco/WEB-INF/web.xml/web.xml the  sections for:

<!-- CORS Filter Begin -->

After Restarting Alfresco, it was working for a while for both, Domain/share/page Actions and CMIS Action. After a while, any Actions on Alfresco Share ends in 500.

CMIS 1.1 Connector works from the Other Machine, AOS & WEBDav works too, only the Share Pages gives out an Error 500.

Anybody an idea?

Can you provide more details of errors, e.g. excerpts from log files and/or error messages contained in the 500 responses?
