BigDecimal throws an ArrayIndexOutOfBoundsException if string ends in 'E'

FULL PRODUCT VERSION :


A DESCRIPTION OF THE PROBLEM :
It assumes that there will always be an exponent following an E. If there isn't, this throws an AIOOBE:

                // exponent expected
                if ((c != 'e') && (c != 'E'))
                    throw new NumberFormatException();
                offset++;
                c = in[offset]; <---- exception

Parsing this invalid string should presumably throw a NumberFormatException, instead.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
new BigDecimal( " 1.234E " );


REPRODUCIBILITY :
This bug can be reproduced always.
