[fedora-java] [BlueJ, Iced Tea, FC8] Getting errors when invoking methods

[Casper Bruun]

Hello!

I just started learning Java at my university. We are using the book
"Objects First with Java"
by David J. Barnes and Micahel Kölling.

To get started with Java on Fedora 8, I installed
java-1.7.0-icedtea-devel - 1.7.0.0-0.19.b21.snapshot.FC8.i586
as well as BlueJ using the .jar file from it's website.

Used this command to start the BlueJ installation:
/usr/lib/jvm/java-1.7.0-icedtea-1.7.0.0/jre/bin/java -jar
bluej-221.jar.
This worked fine and the installation linked to
/usr/lib/jvm/java-1.7.0-icedtea-1.7.0.0 as the JDK directory.

Loaded up BlueJ, imported the first project from the CD that came with
the book. Creating new objects were no problem
at all. However, as soon as I tried to invoke a method, I got this
error: http://pastebin.com/m2efbebbd

Here's a screenshot of BlueJ and the error as well:

Java and Javac version match: http://pastebin.com/m2063432d

Any ideas on what is wrong here? If you need me to supply more info,
please tell me.

Thank you in advance!
