A DESCRIPTION OF THE REQUEST :
  From the Javadoc for Integer.decode(String) in Java 7.

DecimalNumeral, HexDigits, and OctalDigits are as defined in section 3.10.1 of The Java™ Language Specification, except that underscores are not accepted between digits.

However, this section defines a format new to Java 7; BinaryNumeral

A binary numeral consists of the leading ASCII characters 0b or 0B followed by one or more of the ASCII digits 0 or 1 interspersed with underscores, and can represent a positive, zero, or negative integer.

For consistency, this method should decode BinaryNumeral as well.



JUSTIFICATION :
For consistency.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Decode binary numerals.
ACTUAL -
Throws a NumberFormatException

CUSTOMER SUBMITTED WORKAROUND :
