> Sometimes we receive XML signatures that have <Signature> Base64 value provided with many line feed characters and decoding of this value fails. Below is the code to reproduce:
> {code:java}
> String base64 = "PHhtbD5hbGEgbWEga290YTwveG1sPg=\n\n=";
> XMLUtils.decode(base64.getBytes());
> {code}
> and the exception it throws:
> {code:java}
> Exception in thread "main" java.lang.IllegalArgumentException: Input byte array has wrong 4-byte ending unit
> 	at java.util.Base64$Decoder.decode0(Base64.java:704)
> 	at java.util.Base64$Decoder.decode(Base64.java:526)
> 	at org.apache.xml.security.utils.XMLUtils.decode(XMLUtils.java:553)
> {code}
> This problem does not occur on 2.0.10 version.
