When OpenJDK java web start is used, it can not open some jnlp files.
For example, you can try the following ones :
http://www.spark-angels.com/telecharger-1/
http://sweethome3d.sourceforge.net/SweetHome3D.jnlp

If you open them through firefox, it downloads the necessary jars, but does not
open the application.
If you download the jnlp files and launch them whith javaws, you get the
following error :
netx: Spec version not supported (supports 1.0)

These application work if you launch them with Sun Java 6 Web start.

Netx seems to be the library used by openjdk to handle jnlp files. I checked
the source code and it only supports 1.0 version of jnlp (see file Parser.java
in package netx.jnlp). The examples above use version 1.5 of jnlp.

What is annoying is that the upgrade from gutsy to hardy makes openjdk the
default java alternative, even if Sun java 6 was installed.
Thus, the jnlp files that were working under gusty do not work anymore under
hardy.

The workaround I currently use is to choose another location when firefox
prompts me which application to use for jnlp files : I specify
/usr/lib/jvm/java-6-sun/bin/javaws instead of "OpenJDK Java Web Start". So the
jnlp files are opened with Sun Java instead of openjdk : I still need to keep
Sun java.

The solution would be, I guess, to make netx support 1.5 jnlp files. But this
project doesn't seem to be updated for years...
