Hi Mark,
Thanks for the fast respose.

But this is not even stated in the java.util.Iterator javadoc.. and as said
before it could break existing code which runs fine on Sun - and this code
could in worst case be an obfuscated closed-source library, so this lib cannot
run on Gnu classpath while working fine on Sun. 

Just wanted to point out again that this is inconsistent with Sun's classlib
behaviour, though I understand your intent in making the Iterators fail-fast. 

Greetings

Thomas
