           Summary: Kepler-trunk fails to properly read in kar files the
                    first time after they are built.
           Product: Kepler
           Version: 1.x dev
          Platform: Other
        OS/Version: All
            Status: NEW

Kepler from the trunk (hereinafter "kepler-trunk") fails to read kar files the
first time immediately after they are build.

The problem can be reproduced by the following sequence of commands and
associated relevant ouput:

First Set of Commands:
======================
ant change-to -Dsuite=vanilla-trunk
ant update
ant clean-cache
ant run

Relevant Output:
================
run:
      [run] Building Kars...
      ...
      [run] KAR Library directories: []
      ...

At this point, you cannot drag actors to the canvas from the library pane. Shut
down Kepler and run the following command:

Second Set of Commands:
=======================
ant run

Relevant Output:
================
run:
      [run] Building Kars...
      ...
      [run] KAR Library directories:
[/Users/davidwelker/kepler.modules/common/kar/actors,
/Users/davidwelker/kepler.modules/common/kar/directors]
      ...

Now the actors do exist in the actor pane and can be dragged to the canvas.

======
This problem does not exist for kepler-1.0. Since the build system is precisely
the same for kepler-trunk and kepler-1.0, we can infer that the source of this
problem is a change made recently in kepler-trunk. (This conclusion is
reinforced by the fact that this problem did not used occur when running
kepler-trunk.)
