[LANG] Possible bug on NumberUtils.isNumber()?

[EP...@upstate.com]

Hi all,

I am checking whether "1b" is a number, and NumberUtils.isNumber() says it
is...  Is the lowercase b mean binary or something?

Here is my testcase:
 public void testNumberUtilsIsNumber()
    {
        String a = "1b";

        assertTrue("1b is not a number!", !NumberUtils.isNumber(a));
     

    }


And here is my error:

Testcase: testNumberUtilsIsNumber took 0 sec
	FAILED
1b is not a number!
junit.framework.AssertionFailedError: 1b is not a number!
