how to use import sources for C++

Trying the C++ import for existing code. Upon importing the first
message that appears state "Add entries to match the classpath that
would be used to compile these source modules.  For example, you
probably want to include the JRE or JDK that you use."
This stumps me as I am not using Java and thus certainly don't want the
C++ code compiled with a java compiler. Since argouml started, the JRE
is ok.

Thus happily ignoring the dialogue, clicking ok, getting another
dialogue telling us some limitations, fine for me, pressing close. And
yet another box with an error report:

Is it just broken or is there a nack i didn't recognise?
