Description

LinuxContainerExecutor.java

      ... ...
      if (LOG.isDebugEnabled()) {
        LOG.debug("Resource handler chain enabled = " + (resourceHandlerChain
            == null));
      }
      ... ...

I think it is just a typo.When resourceHandlerChain is not null, print the log "Resource handler chain enabled = true".
