NPE in PrismFontLoader.java: Loading primary font factory failed

[Kevin Rushforth]

Do you have the pango and freetype libraries installed on your platform? 
One thing to check is whether any dependent libraries are missing for 
the following .so files:

    ldd  libjavafx_font.so
    ldd  libjavafx_font_freetype.so
    ldd  libjavafx_font_pango.so
