Please, observe 'example' section for j.l.i.MethodHandles.whileLoop(...)

The example uses MethodHandles.doWhileLoop(...):
MethodHandle loop = MethodHandles.doWhileLoop(MH_initZip, MH_zipStep, MH_zipPred);

Changing 'doWhileLoop' to 'whileLoop' leads to IAE because whileLoop and doWhileLoop have different arguments order. Changing arguments order to

MethodHandle loop = MethodHandles.whileLoop(MH_initZip, MH_zipPred, MH_zipStep);

resolves problem.
