Cannot load font in JRE 8

Question

I cannot load a font from an S3 Inputstream in JRE 8. I do not have issue if a system is installed with JRE 7, JDK 7, or even JDK 8.

val fontInputStream = s3         


        

Answer 1

It turns out that this is a problem with the openjdk-8-jre-headless installation. This is the installation in the Docker image for java 8 JRE. I simply install openjdk-8-jre (without headless) and the problem goes away.

If you look at the error log, the loading of the font require awt X11, which is missing from headless version of JRE.
