           Summary: SubsetConfiguration.getKeys() always appends "."
                    delimiter to prefix
           Product: Commons
           Version: unspecified
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Configuration
        AssignedTo: commons-dev@jakarta.apache.org
        ReportedBy: timothomas@web.de


When creating a SubsetConfiguration object, e.g.

conf = new SubsetConfiguration(parentConf, "myprefixwithadot.");

calls to conf.getProperty("prop") result in a call to
parent.conf(conf.getPrefix() + "prop") as expected.

However, a key iterator obtained by calling conf.getKeys() will only iterate
over keys starting with (conf.getPrefix() + "."). In the example, this will be
"myprefixwithadot..". There should not be a dot appended. 

The error is probably caused by line #283 in AbstractConfiguration.java

return key.startsWith(prefix + ".") || key.equals(prefix);
