jnlp not honoring custom xml parser property?

[Dan Rollo]

Hi Jiri,

Just to clarify, I am only using IcedTea on my Raspberry Pi (arm), and 
the problem of using a custom endorsed library only occurs on Raspberry Pi.

The jvm I use on my Ubuntu x86_64 machine is OpenJDK:
$ java -version
java version "1.7.0"
Java(TM) SE Runtime Environment (build 1.7.0-b147)
Java HotSpot(TM) 64-Bit Server VM (build 21.0-b17, mixed mode)

My reason for mentioning that this same .jnlp file/webstart app works 
fine under Ubuntu is to show that the .jnlp file syntax, etc is valid.

Anybody returning from vacation have other ideas?

Thanks!
Dan
