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

             Summary: Duplicate copies of InputStreamUtil.java and 
DynamicByteArrayOutputStream.java classes in client.net package
                 Key: DERBY-5786
                 URL: https://issues.apache.org/jira/browse/DERBY-5786
             Project: Derby
          Issue Type: Task
            Reporter: Mohamed Nufail
            Assignee: Mohamed Nufail
            Priority: Minor


In solving [DERBY-4491|https://issues.apache.org/jira/browse/DERBY-4491], 
InputStreamUtil.java and DynamicByteArrayOutputStream.java classes which are 
present in org.apache.derby.iapi.services.io package was needed for the network 
client also. So now there are duplicate copies of those classes in 
org.apache.derby.client.net package. 

But the client uses only a small part of the functionality those classes 
provide. In a discussion in dev list 
(http://mail-archives.apache.org/mod_mbox/db-derby-dev/201205.mbox/%3Cwjo8r4ucgtfv.fsf%40oracle.com%3E)
 it was decided to use EncodedInputStream.PublicBufferOutputStream which is 
already in the client.net package instead of the duplicated classes. In order 
to do this PublicBufferOutputStream will first be made into a stand-alone class.

Doing this would help to reduce the code size and increase code coverage, as 
the duplicate classes currently have no code coverage.
