Julius Davies commented on CODEC-140:
-------------------------------------

"Hello" is a valid Base64 encoding.   Not all UTF-8 strings return true.  C=
onsider the following:

{code}
    /*
      Prints the following:

      Hello: true
      Ol=C3=A9!   false
      Hello! false
    */
    System.out.println("Hello: " + Base64.isBase64("Hello"));
    System.out.println("Ol=C3=A9!   " + Base64.isBase64("Ol=C3=A9!"));
    System.out.println("Hello! " + Base64.isBase64("Hello!"));
{code}

> I just called Base64.isBase64("Hello") for instance and it returns true. =
I thought it would return true only if it is valid base64 encoded string.
