I believe that much of the work Sun had done on Self found its way to Java in the form of HotSpot.

[hipitihop]

Not to take anything from Self, but in regards to HotSpot, a more accurate history attributes the lineage to Smalltalk and the Animorphic team. Some details here https://en.m.wikipedia.org/wiki/HotSpot

Right. Sun incorporated Animorphic's work into Self, and later purchased Animorphic and the technology became known as HotSpot.
