Hmm... Pre-Harmony, the IBM VM + classlib used the same thread library. When the classlib was contributed, I guess they forked the thread lib and changed the names of the functions. (I'm only speculating since I wasn't involved in that process.) hythr should be virtually identical to a subset of j9thr23.dll.
I agree, the IBM VM + classlib should be using the same thread library. It shouldn't be hard to implement a redirector lib from hythr to j9thr. Would this obsolete the current classlib hythr implementation? Angela On 11/13/06, Andrey Chernyshev <[EMAIL PROTECTED]> wrote:

Seems like we don't have any VM at the moment which would be really using the hythr from classlib. Even IBM VME doesn't use the hythr. As Tim wrote earlier, VME is using it's own threading library called j9thr23 [1]. Does it differ a much from the hythr? Guess it might be favourable for the classlib + IBM VME stack as well if it was using a single thread library. Would it be possible for VME to include a straightforward hythr implementation which can delegate hythread_* calls to the j9thr23? Thanks, Andrey.
