问题
I am trying to upgrade all my java application to openJDK11 ( from Oracle 8 ). and I notice one problem in my reporting server which use Pentaho.
It seems that the Excel autosize feature requires libfontconfig.so in openJDK11,
however I can find the module at /usr/lib64/libfontconfig.so.
Any way to solve this?

Update :
after putting '-Dsun.java2d.debugfonts=true' I got this logs :

Did not find a fontconfig file.
回答1:
Solved by doing 2 things ( implemented using docker ) :
add configuration variables :
this is needed to let JDK know where is the location of libfontconfig.so
ENV LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:/usr/lib/:/usr/lib64/"
add default files to JDK/lib folder:
This is needed because openjdk does not have it by default. the below files are coming from Oracle JDK8
ADD ./src/main/resources/fontconfig.bfc /opt/jdk11/jdk-11.0.1/lib/fontconfig.bfc ADD ./src/main/resources/fontconfig.properties.src /opt/jdk11/jdk-11.0.1/lib/fontconfig.properties.src ADD ./src/main/resources/fonts /opt/jdk11/jdk-11.0.1/lib/fonts
Update : the above solution works, but sometimes after the redhat linux loaded, it seems not able to find the font and giving the "java.lang.ClassCastException: class sun.font.CompositeFont cannot be cast to class sun.font.PhysicalFont (sun.font.CompositeFont and sun.font.PhysicalFont are in module java.desktop of loader 'bootstrap')". After 10-30 mins, the issue disappears.
Solution for this :
Adding extra TTF files ( for me it was calibri.ttf ) and copied to /usr/share/fonts/TTF
execute this command : fc-cache -fv This to ensure the font loaded immediately by the fontconfig.
ADD ./src/main/resources/fonts/*.ttf /usr/share/fonts/TTF/ RUN fc-cache -fv
