jnlp not honoring custom xml parser property?

[Jiri Vanek]

Hi Dan!

Thank you for reporting!

I'm afraid that you are right, however both our leading icedtea-web guys are on vacation so they will confirm later.

No, this is exactly the best list for this:)

This sentence make me doubt about my original words that we are not supporting. It actually looks like we are :).

You can see that there is different JVM on your raspberry.  There is Zero, and on  ubuntu you wil have HotSpot. Although I doubt it a bit, there can be some more differences.

Yap, what java do you have on your ubuntu adn what are versions of icedtea web?  (javaws -about)

I must admit I have never testes icedtea-web on zero :(

Also it is possible that this is icedtea-web bug, but zero bug. Because icedtea-web is doing nothing more then forwarding those params to JVM.

I will ask Pavel (cc'ed) if he ever tested zero in such manners.


Thanx again for reporting!
