Configuration 1 : jEdit 4.5pre2 (2012-01-27) + official SideKick (1.2), JavaSideKick (3.1.2), PV (3.4.0)
Bug 3382969 has been fixed in the trunk but not yet released ==> jEdit still freezes from time to time.
Configuration 2 : same as before + Classpath plugin
==> there are two classpath entries in the Project's configuration panel
Configuration 3 : same as before but with daily build of the 4 plugins from http://www.tellurianring.com/projects/jedit-daily/
==> single classpath entry in the PV
==> completion is broken
(still completes for java objects from jre, but not for objects of my project).
classpath defined in the Classpath plugin options -> completion not work*
classpath defined in the Project Panel options -> completion not work*
classpath defined in both -> throws "Ambiguous Classname" all the time
*just hear my computer's fan one or to seconds while searching how to complete...
