Although I have a Java-VM installed in the system (sun-jdk-1.4.2.14) I put the recommended version (j2sdk1.4.2_05) into the `linux' subdirectory of $HOME/OpenFOAM and adjusted `JAVA_HOME' $HOME/OpenFOAM/OpenFOAM-1.4/.bashrc accordingly.

This is what foamInstallationTest outputs:

What is wrong? Help is greatly appreciated.
