I interpret InternalError as meaning something wrong with the JDK itself, not
something in the environment causing
a problem, so RTE would be fine here.
But this NPE is coming from a field (head) that is initialised by code that
reads a binary font configuration file.
Are you quite sure you've diagnosed the root of the problem ? Or that this
message is really in the right place ?
What does -Dsun.java2d.debugfonts=true reveal ?
