I'd love to hear why you think this design is problematic as opposed to 
one that lets users accidentally expose synchronization issues to 
consumers of their API surface, which is what many people end up doing 
since synchronized (this) or even synchronized (this.classinfo) are 
allowed at all.

(I've seen countless cases of those two horrible abuses of synchronized 
especially from people asking questions on e.g. IRC.)
