Hi,
I don't remember seeing this issue but a one second search on google for
the error
message seems to point to a broken OpenJDK installation, which has been
common for example on docker, e.g.:
https://github.com/docker-library/openjdk/issues/73
Full search:
https://www.google.it/search?q=sun.awt.fontconfiguration.getversion+nullpointerexception&oq=sun.awt.FontConfiguration.getVersion+null

Cheers
Andrea
