Hi Warren,

This sounds cool! However, since we're trying to create a _compatible_ Java 
implementation, adding new public methods to the
standard classes is a bad idea!

Instead, I would suggest that this stuff gets activated via a system property 
(eg "gcj.dumpobjects") that can be set either by
calling "System.setProperty()" or by using the -D option at compile-time.

Even better, why not make a small utility (ala 'jcf-dump') that hooks into 
ObjectInputStream and gets installed with libgcj, ie
'ser-dump' or something?
