Note that Java is not used to actually display the documentation - it appears in a notebook. HTML documentation would be greatly inferior however, because you could not actually execute documentation cells (possibly with changes). I suspect WRI have bought in some Java search component that is too inefficient - hopefully they will re-code it in a faster form, possibly inside Mathematica, in C.
