Fix for Bug #38582.  Since Chainsaw moved out into it's own SVN repo,
it appears that the distribution no longer built all the Receiver Java Doc (because
they are still in the log4j source path.

Changed the build sequence so that to get the JavaDoc for Receivers requires the 
location of the log4j source code.  Failing to have this just means that Chainsaw
doesn't have all the JavaDoc embedded.
