[Bluej-discuss] Cannot create an instance of Class.

[Torsten Otto]

Hi all,

this is something I would like to be more obvious, too. There is no  
good place to find out about this and also the broken arrow symbol  
which proves even more cryptic.
Maybe an appendix in the 4th edition with images of these would be  
good or a tool tip on mouse over in BlueJ directly.

Regards,
Torsten Otto
