Description Marc Schoenefeld 2008-04-16 05:16:44 EDT
Strings are immutable in Java, so the trim() method on strings returns
a value of the trimmed value. PropertiesUtil ignores the return 
value and uses the original (untrimmed) value. Therefore effect-dead 
code unless the "nextValue.trim()" is not rephrased to 
"nextValue = nextValue.trim()".

   public static Properties trim(Properties properties)
        Properties trimmedProperties = new Properties();

        // Loop over all the properties
        for (Iterator i = properties.keySet().iterator(); i.hasNext();)
            String next = (String) i.next();
            String nextValue = properties.getProperty(next);

            // Trim the value if it is not null
            if (nextValue != null)

            // Store the trimmed value in the trimmed properties
            trimmedProperties.setProperty(next, nextValue);

        return trimmedProperties;
Comment 1 Rajith Attapattu 2009-04-21 09:52:24 EDT
I have removed this particular method from the PropertiesUtil class from r756231 on Qpid trunk.
So this should not longer be a problem.
Comment 2 ppecka 2012-07-10 04:38:19 EDT
[root@qpid trunk]# svn log -v -r756231
r756231 | rajith | 2009-03-19 18:00:34 -0400 (Thu, 19 Mar 2009) | 3 lines
Changed paths:
   D /qpid/trunk/qpid/java/client/src/main/java/org/apache/qpid/nclient/JMSTestCase.java
   D /qpid/trunk/qpid/java/common/src/main/java/org/apache/qpid/util/PropertiesUtils.java

These classes are not used in any meaningful way.
I am removing them to avoid any confusion they may cause.


since the classes were removed, marking this issue as VERIFIED
