Synchronization in java.util.Collections

[Dalibor Topic]

Hi,

I've looked over Classpath's implementation of
synchronized* methods in java.util.Collections, and I
don't understand why the synchronized wrapper classes
sync on their own specific mutex field instead of
syncing on themselves?

i.e. why not have all the wrapper methods synchronized
and drop the mutex field? That's how kaffe does it.

best regards,
