             Summary: Use java.util.Base64
                 Key: ARTEMIS-5048
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-5048
             Project: ActiveMQ Artemis
          Issue Type: Improvement
            Reporter: Justin Bertram
            Assignee: Justin Bertram


We've traditionally used {{org.apache.activemq.artemis.utils.Base64}} for 
Base64 encoding/decoding. This implementation is based on public domain code 
from http://iharder.net/base64. 

In Java 5 {{java.util.Base64}} was introduced. I assumed we hadn't switched to 
this implementation for performance reasons so I created a simple JMH-based 
test to compare the two implementations and it appears to me that 
{{java.util.Base64}} is significantly faster than our current implementation. 
Using the JDK's class will simplify our code _and_ improve performance. Also, 
it should be 100% backwards compatible since Base64 encoding/decoding is 
standardized.
