icedtea/java backport someone?

["dE ." <de.techno@gmail.com>]

I've upgraded to iceweasel 20 and I think cause of this upgrade, the icedtea plugin or the Java VM is giving problems.

Whenever a page with a java applet starts, I get this on the console --

Actually it varies with the applet being loaded; some result in -- 

java.lang.NullPointerException

But point it no applet works.

I head this's a icedtea VM bug. So can someone please backport the current stable version of the 1.7 API?
