java version "1.3.0rc1"

BigDecimal Constructor for String throws
StringIndexOutOfBoundsException when the String has length of 0.

This is due to the fact that the constructor for the String
arguement has newly added code to check for signs; its the first
statements executed in the BigDecimal class, String Constructor,
under the comment "Deal with leading plus sign if present".  This
code was added with release 1.3.  Release 1.2 throws a
NumberFormatException.  This may be related to bug 4259453.
