ADDITIONAL SYSTEM INFORMATION :
Linux (Technically I expect it to affect any OS with varying Exceptions, but Linux there are real cases)

A DESCRIPTION OF THE PROBLEM :
On systems with no fonts installed creating and using AWT Fonts (from files or streams) causes an exception (see first stack trace in Actual Result). It would be preferable if those Exceptions would not happen, at least not until it is necessary, e.g. when the non-existing default-physical-font is required.

If this is too much of a change in behavior, making it configurable, e.g. via the command-line, would also work, but changed default behavior would be ideal.

On Linux there is also an Exception (second stack trace in Actual Result) when fontconfig is missing. that should ideally also be changed in the same way.

ACTUAL -
java.lang.Error: Probable fatal error: No physical fonts found.
