BI Publisher font mappings (Defaults and Additions).
Missing fonts Directory in bi/common and no default fonts files (.ttf/TTF) in directory, therefore font mappings will not work for RTF and PDF
I fixed the problem.
1. I've copied the font folder with all the fonts to bi/common;
2. Copied the font folder with all the fonts to /oracle_common/jdk/jre/lib
3. Set the JAVA_HOME variable to /oracle_common/jdk/
4. Restarted the machine
I don't know exactly which step is the right fix but this worked for me.
