Fatal: Read Error: Could not read or parse the JNLP file

[Min Hua]

Jiri, et al.

Thank you all for your quick response to the bug report I submitted.

I've downloaded and installed the application software locally on my 
computer so I don't really need to run it via web launch jnlp. However 
it's helpful for others for their use in other applications if this bug 
can be fixed for next release of IcedTea Web Start.

best regards,
- Min
