java webstart creates infinite open windows, desktop DoS

[Peter Petrakis]

To recreate the issue, open this sample JNLP file:
http://pscode.org/jws/basicserv.jnlp

A series of new windows will open, blank, one after the other,
with no end in sight.

It's so bad I had to switch to a tty and killall -9 firefox.

The behavior is the same if you were to download the jnlp instead
and use "gnome-open basicserv.jnlp".

However, if I were to use 'javaws basicserv.jnlp', the service
spawns just fine. If I change firefox to call javaws directly, it
also works just fine. This leads me to believe that there's a bug
in the mime handling for JNLP.

To ensure it wasn't some desktop setting I did a "unity --reset" and
also performed the same tests from metacity with the same
results.

I get this too on precise with FF 9. I think Peter had at one point said "Open this filetype with Firefox automatically from now on" at one point, because I just get the standard "how do you want to open this downloaded file?" dialog, which defaults to Firefox.

If I open the downloaded jnlp file, it opens a new tab and I just get the same dialog again. So I can confirm the infinite loop nature of this.

I'm able to reproduce this , Chris could you please have a look ? thanks.

Hi,

I can confirm the problem:

I have a Supermicro X9SCM-F mainboard which uses Java Webstart for the IP KVM.

When I try to open the remote console, I get an endless loop of new tabs opening the .jnlp file from /tmp

[stephen mulcahy (stephen-mulcahy)]

Experiencing same problem on Ubuntu 11.10 running Firefox 10.0.2 with sun java6 plugin installed
Connecting to a supermicro kvm
Tabs keep opening firefox

[stephen mulcahy (stephen-mulcahy)]

Can fix by downloading jnlp file
Right click on file and change properties such that it is opened with Sun Java Webstart rather than a Browser (not sure whether I set that at some stage or whether it was set automatically)

Still same problem her (Ubuntu 15.04 Firefox 40.0).
