java.lang.NullPointerException: name can't be null

[andreatera]

Hi,

we do get following error since version 1.10.0 (Windows only):

net.sourceforge.jnlp.LaunchException: Fatal: Read Error: Could not read or parse the JNLP file at 'file:/C:/Users/XXXX/Downloads/client.jnlp'. You can try to download this file manually and send it as bug report to IcedTea-Web team.

Some notes:

• we do use bellsoft-jdk11
• with the same JNLP file until OWS version 1.9.1 it worked well.
• on Linux Ubuntu with the same OWS version the issue doesn't appear.

Following the masked client.jnlp for reference.

Along the lines of #545, #450, #226
Happened to me when proxy settings where initially wrong and then corrected.
