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.
