#891 Cannot Invoke HJ Methods from Interactions

[Mathias Ricken]

We cannot call methods directly from the Interactions pane: We have to use the hj or run commands, otherwise the class loader isn't properly set up. We should at least come up with a better error message than throwing an exception:

Welcome to DrJava. Working directory is /Users/mgricken/bin/hj.release/examples

java.lang.NullPointerException
