Description

I found this while trying to setup some automated testing against JDK9, but it can also affect users of java8/java7 depending on how their JDK/JRE is packaged.

Some JVM packagers (in particular debian JVM "*-headless" packages) do not install any fonts along with the JDK/JRE, nor do these pacakges depend on any other packages providing fontconfig support for the JVM to pick up dynamically.

This can cause problems when using
XLSXWriter – notably in the form of errors that look like this...

The solution is to ensure your JVM has proper font support – most likely by ensuring the neccessarily font packages are installed (in the case of debian, installing the libfontconfig1 package should fix this problem.)
