Steve,
There's no attachment .. and this should be discussed on 2d-dev, not
core-libs.
I do see in the code where the null de-ref can happen. This is some new
JDK 7 code.
Although a system where the library is missing is basically DOA for
client use.
I'd suspect you are running 32 bit JDK on a 64 bit Linux which hasn't had
the 32 bit libs installed. If so, likely you'll run into other problems too.

Hi all, a problem was discovered on JDK7 when using the Nimbus L&F on
a system where libfontconfig.so was not installed (On AIX actually but
in theory on any unix system)
Under the covers Nimbus uses the sun.font.FontConfigManager to
retrieve fonts. sun.font.FontConfigManager in turn is intended to use
(for a unix system) the libfontconfig.so system library if present.
The code is intended to cope with the library being missing but it
unfortunately doesn't. A array is referenced without checking if it is
null. On systems where the system library is present this array is
never null but in this specific case the array is null and the
reference fails as follows.

The fix is trivial (see attached) and probably just tactical.
Cheers,
