We had some problem yesterday with our application that is launch from webstart. Everyone that upgraded to JRE 6 update 10 had the problem. This morning we don't have the problem. We are all on Windows Xp 32 bit, english or french and we all use a proxy.
I suspect that the problem is related to how update 10 handle the proxy responses.
here a
screenshot that I took yesterday.
the workflow was this :
we had a jnlp and when we click on it.. javaws starts and we got this popup. We can close it, and the application will download, and before the application starts.. we had the popup again.. close it again.. and the application run perfectly.
here a screenshot of my proxy setting in
IE and
firefox : (the default browser is FF)
