Here is a code from default jspwiki.properties :

#############################################################################
#
#  Plugin search paths.
#
#  Define here the packages you want to use for searching plugins, 
#  separated with commas.
#  For example, use the following command to add "org.myorganisation.jspwiki.myplugins"
#  and "com.foobar.myplugins" to the search path.
#
#  The default path is "com.ecyrd.jspwiki.plugins", and it will be always
#  the last item on the path.  This allows you to override JSPWiki default
#  plugins.  Note that you are only adding to the path, not replacing it (ie.
#  the default path is never removed.)
#
#  jspwiki.plugin.searchPath = org.myorganisation.jspwiki.myplugins,com.foobar.myplugins
#
jspwiki.plugin.searchPath = 

#############################################################################
#
#  Page filters

When we use default path, than (for example) search does not work. That is because of wrong default path. The real path is: The default path is "com.ecyrd.jspwiki.plugin" (without "s" in the end)
I spend a time for finding, why "search" does not work. :) Please, correct this in the next release.

P.S. Maybe, this is a reason, why do not work "Incoming Links" and "Outgoing Links"...

Well, this is just a small bug in the comments... It's been there for a couple of years, so I don't think it's impacting anything else :)
