             Summary: NumberUtils#isNumber() returns false for "+2" and true for "-2"
                 Key: LANG-1038
                 URL: https://issues.apache.org/jira/browse/LANG-1038
             Project: Commons Lang
          Issue Type: Bug
          Components: lang.math.*
    Affects Versions: 3.3.2, 3.1
            Reporter: will mason


The strings:

    +2
    +  2

Give a "False" result when tested by isNumber().  Case one, "+2" is legal with Integer.parseint().  Case two: "+  2" gives an exception with Integer.parseInt().

I believe the function should match legitimate inputs for the respective parser function depending on the number type.

Workaround:

Use something like:

  NumberUtils.isNumber( wrkStr.replaceFirst( "\\+", "") )
