: Through its history, CORBA has been plagued by shortcomings in its implementations.

Often there have been few implementations matching all of the critical elements of the specification, and existing implementations were incomplete or inadequate.

As there were no requirements to provide a reference implementation, members were free to propose features which were never tested for usefulness or implementability.

Implementations were further hindered by the general tendency of the standard to be verbose, and the common practice of compromising by adopting the sum of all submitted proposals, which often created APIs that were incoherent and difficult to use, even if the individual proposals were perfectly reasonable.
