Unfortunately, I have not been able to recreate
this problem with a small test case.
My java application consistenly crashes when
displaying on some of the NCD X-terminals that
we have in-house. The problem goes away when
we switch the NCD terminal to use a font server,
so the problem has something to do with fonts;
but the NCD has not complained about any
requested fonts not existing. Perhaps the
NCD fonts are missing some piece of information
that the Java code is relying on, or returning
that information incorrectly, and the Java code
is then crashing.

A traceback is included below.

Other odd behaviors related to fonts:

When creating one of my forms, the client asks
for the same fonts over and over again. Not only
that, it asks for about ten different fonts (about
ten times each!) when in fact there appear to be
only two fonts used in the form. When the NCD
X-server is modified to have fewer fonts available,
the number of fonts requested goes way down, and
it doesn't ask for the duplicates. Perhaps there
is a bug whereby, when it gets confused, it asks
for the same font many times?

One of the fonts in the form gets changed from
the default to a larger font. It sometimes
(depending on the font path setting for the NCD
terminal) comes out as an italic font, though it
should not be.
