[jxpath 1.2] Why does InfoSetUtil.booleanValue method handle strings in the manner that it does???

[Tom Muldoon]

Can anyone explain why the InfoSetUtil.booleanValue(Object object) method 
returns true when the object is a String if and only if it is a non-zero length 
string? Here's a code excerpt ...

        else if (object instanceof String) {
            return ((String) object).length() != 0;
        }
Is this a bug? Shouldn't it return true if and only if the string is equal to 
"true" (ignoring case, of course)?

Thanks in advance, Tom
