Thanks for the review.
If you analyse "definition", it is not constant and changes as the state 
of the class changes (whether binary class is loaded, whether it
has been compiled and so on) - and so does the status field. The type 
field looks like the only good candidate to use in the equals method -
so the equals() looks correct to me.
Now the question is whether there is any need of overriding 
Object.equals() at all, that is, whether each ClassDeclaration object should
be treated as a unique one - I am looking around in the source code to 
check that.
