Wiki pages containing internal links does not render after 5.0.d -> 5.2.0 -> 7.1.0 update.
I decided to update my old Alfresco community server from 5.0.d to 7.1.0 community (docker container). Since the update, the wiki pages that contains internal link (e.g. [[my internal wiki page]]) trigger an exception in the alfresco app:
If Alfresco dev could include this in their source, that would be nice. Basically, devs should check for any old version of org.apache.commons.lang.StringEscapeUtils and use org.apache.commons.lang3.StringEscapeUtils instead.
