java plugin fails test with OpenJDK7

[Andreas Radke]

Running ArchLinux we provide both latest OpenJDK6 and OpenJDK7 releases
together with icedtea-web 1.1.4. The Plugin test page
http://www.java.com/en/download/testjava.jsp works well with java ver6
but fails with ver7. The Oracle prebuilt 7u2 jre shows the plugin test
well again.

Any idea? I get this in the non-debug output:

Do Mozilla (Firefox 9/ built with Xulrunner 8, also tested npapi-sdk) guys block the old ver.7 java 
release or is this a bug? I can provide a debug log if needed.
