[Antonio Sanso (JIRA)]

----------------------------------

             Summary: Wrong regex in TokenReader
                 Key: OLTU-200
                 URL: https://issues.apache.org/jira/browse/OLTU-200
             Project: Apache Oltu
          Issue Type: Bug
            Reporter: Antonio Sanso


The regex in TokenReader [0] doesn't comply with the JWS spec.

The spec [1] says:

{code}
BASE64URL(UTF8(JWS Protected Header)) || '.' ||
     BASE64URL(JWS Payload) || '.' ||
     BASE64URL(JWS Signature)
{code}

while the impl regex is 

{code}
private final Pattern base64urlTokenPattern = 
Pattern.compile("([a-zA-Z0-9/+=]+)\\.([a-zA-Z0-9/+=]+)\\.(.+)");
{code}

it should be rather

{code}
private final 
Pattern.compile("([a-zA-Z0-9-​_=]+)\\.([a-zA-Z0-9-_​=]+)\\.([a-zA-Z0-9-_=]+)
{code}
