[jira] [Commented] (DERBY-5845) Remove unused class URLFile.java

["Bryan Pendleton (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DERBY-5845?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13406241#comment-13406241 ] 

Bryan Pendleton commented on DERBY-5845:
----------------------------------------

According to the comment at the top of URLFile.java:

        It is used by the database engine to access persistent data 
        and transaction logs under the classpath subsubprotocol.

The "classpath subsubprotocol" is one of the more puzzling and
less-understood parts of Derby. See, for example, 
https://issues.apache.org/jira/browse/DERBY-5612

Maybe if you look at some of the examples in that JIRA issue, it
will give you some ideas to see if you can force URLFile to be invoked.

> The file URLFile.java in the package org.apache.derby.impl.io seems to be unused. 
> Emma reports have 0% code coverage for this class.
> My manual search didn't result in any reference of this class at all.
> Looking at the svn history, seems that this class was last modified on 09/08/2006 and no changes since then.
> So this makes it a suitable candidate for removal. 
> Any suggestions ?
