Source works in NetBeans but not with java/javac

[jacsoft]

Hello,

I have created a program and it seems to work in NetBeans. Now I am trying to compile it with the commandline compiler. I can get it to compile with:

javac Main.java

It gives no error and makes a class.

Now I run the program with:

java -classpath . Main

It then seems to be running. It asks for input. If I give the same input in the running NetBeans as in the commandline version then it always works in the NetBeans version and in the commandline version I get strange errors.
It is often an ArrayIndexOutOfBounds on the following line:

                 s = subResultaat2.split("øø")[1];

But the same thing does work in NetBeans. Anyone any clue what it could be?

/update:

Does it maybe have something to do with my scanner?

[CODE] scanner = new Scanner(System.in, "ISO-8859-1");
scanner.useDelimiter("\n|\r\n|\r");
