Bug#708543: geogebra: Geogebra crashes now on start

[Nicolas Patrois]

Package: geogebra
Version: 4.0.34.0+dfsg1-1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

Geogebra used to work with Wheezy.
Now, it crashes on start:

> geogebra 
Exception in thread "main" java.awt.HeadlessException
	at java.awt.GraphicsEnvironment.checkHeadless(GraphicsEnvironment.java:207)
	at java.awt.Window.<init>(Window.java:535)
	at java.awt.Frame.<init>(Frame.java:420)
	at java.awt.Frame.<init>(Frame.java:385)
	at geogebra.SplashWindow.splash(SplashWindow.java:178)
	at geogebra.GeoGebra.main(GeoGebra.java:79)

In fact, I don’t know if it’s a Java bug (wrong version of Java) or a Geogebra bug.
