Re: NPE in PrismFontLoader.java: Loading primary font factory failed

[Maurice]

For those searching for an answer, I could fix it by adding pango and 
fontconfig to the Yocto build.

It seems that pango isn't present on the system. Given that we have a 
fairly naked Yocto image, is there another way than trail and error to 
know all dependencies needed by Java and JavaFX?

Yes, in lib/arm these libraries are present. I'm using the Oracle ARM

Another thing that might help diagnose which library has the problem is 
to run with "java -Djavafx.verbose=true ..." -- that option will print 
each native library as it is being loaded and print the exception 
message if one fails.
