Performance: UTF-8 writer byte[] and char[] buffers should be reused
--------------------------------------------------------------------

                 Key: XALANJ-2368
                 URL: https://issues.apache.org/jira/browse/XALANJ-2368
             Project: XalanJ2
          Issue Type: Bug
          Components: Serialization
    Affects Versions: The Latest Development Code
            Reporter: Michael Glavassevich


Every time a UTF-8 encoded document is serialized, a new instance of 
WriterToUTF8Buffered is created which in turn creates a 16 KB byte buffer and a 
10 KB char buffer.  When the serializer is used to serialize small (around 1 
KB) documents the overhead of creating and garbage collecting these buffers is 
extremely large.  Reusing the buffers would significantly improve the 
performance.
