Bug#904493: geogebra: Geogebra does not start due to error in checking of Java version

[wzab]

Package: geogebra
Version: 4.0.34.0+dfsg1-5
Severity: important

Dear Maintainer,

Whenever I try to start geogebra in my system, I get the following output:

$ geogebra --Xms 64
java.lang.StringIndexOutOfBoundsException: begin 0, end 3, length 2
	at java.base/java.lang.String.checkBoundsBeginEnd(String.java:3317)
	at java.base/java.lang.String.substring(String.java:1874)
	at geogebra.util.Util.getJavaVersion(Util.java:286)
	at geogebra.gui.app.GeoGebraFrame.init(GeoGebraFrame.java:202)
	at geogebra.gui.app.GeoGebraFrame.main(GeoGebraFrame.java:196)
	at geogebra.GeoGebra.startGeoGebra(GeoGebra.java:103)
	at geogebra.GeoGebra.main(GeoGebra.java:88)

Version of Java in my system is:
$ java --version
openjdk 11 2018-09-25
OpenJDK Runtime Environment (build 11+17-Debian-2)
OpenJDK 64-Bit Server VM (build 11+17-Debian-2, mixed mode, sharing)

With best regards,
Wojtek
