I can replicate this bug every time. This is a severe problem, as it makes any Java application using a modal file chooser unusable.
I requested a backport a while ago. It is still pending approval:
I will ping once more, and if nothing comes of it soon, I will just add it to IcedTea.
Doh. Please ignore the comment above. I confused this bug with another one :/
I will take a look at this on Monday.
Thanks. Also worth noting: This bug did not exist in java-1.6.0-openjdk-184.108.40.206-57, the previous version of the package.
Deepak, I know this is the wrong bug but for whichever bug that was meant to be on...
The patch should go in IcedTea now. Even if we finally get it into OpenJDK6, it's going to be an undefined time before that makes it through to end-users.
Fixed upstream. It will be in the next update:

I know this is not the ideal place to ask (please tell me where I should ask or where I should find the answer!) but now that I've installed icedtea7, how do I get it to be used by firefox (or chrome for that matter)?
I did get eclipse to use it.
You will have to rebuild icedtea-web as well:
Once installed, you can link to the IcedTeaPlugin.so (installed in /usr/lib by default) from /usr/lib/mozilla/plugins). You should uninstall the existing icedtea-web RPM too.
Assuming this issue is the main reason you built IcedTea7, I would suggest waiting for a few days. A Java security errata is due on the 18th/19th of October, and will contain this fix.
I've been imagining that the iced tea plugin depends on the java version.
But unlike the java openjdk packages, yum doesn't show any mention of java version for iced tea web. I see in iced tea web control panel that use of multiple jre's is not supported, but I also don't see where to select which SINGLE jre you want to use.
Waiting a few days will give me a new version of the IcedTeaPlugin
using java 6 or 7?
yum list installed
icedtea-web.x86_64 1.1.3-1.fc16 @updates-testing
But how can I tell whether that's 6 or 7?
It will be using Java 6.
