Hello Jakob,
For me your log errors looked like compiled with old Java compiler and
I am pretty sure Sun JDK 1.4.2_08 will print different information
when invoked as java -version (please check it on platforms you were
able to compile on succesfully). So I would assume it is a java
configuration problem. Please verify that your JAVA_HOME is set to Sun
JDK 1.4.2_08 and you have java executable for Sun JDK 1.4.2_08 on
path.
Regards
Piotr
