Issue222869

JPython raises exceptions when trying to read a certain float value (in the
example 
below) from a binary pickle file.  The exception raised depends on what else is
in 
the file.  It works fine if I use dumps/loads instead of dump/load.  CPython has
no 
trouble with the same value, and the file produced by CPython is the same as the
one 
produced by JPython, so I am pretty sure the problem is in JPython's loading. 
The 
same problem occurs (in JPython and not CPython) if I use the pickle module from

CPython 1.5.2


cPickle.dump(-0.094246583493305419, open('j','w'), 1)
cPickle.load(open('j'))

Fixed, but the files must be opened in binary mode.
