This issue has been reported by the Google team today. The Ocelot version is v3.0-rc7.
They got an error when trying to save some files. I've attached one of those files to the issue.
The Ocelot log reports the following error:
String ']]>' not allowed in textual content, except as the end marker of CDATA section
The attached file contains some xml text embedded in iws tags. In this text '<' and '>' characters are encoded as '&lt;' and '&gt;'
When Okapi reads the file, it changes the '&gt;' to '>'. The issue is generated when the final part of a CDATA marker is found: the string "&lt; ! [ CDATA[....]]&gt;" becomes "&lt; ! [ CDATA[...]]>" and the parser gets an error when Ocelot tries to save this content.
