I see how ConstantDesc gets initialized during initialization of 
VarHandle from
your stack trace.  I can't reproduce it and so I assume it was triggered 
by your
local change.  In any case, converting String.format to string concat is 

I am sure Claes may look at the startup and class initialization if we 
can avoid
loading VarHandleDesc from clinit.
