ptolemy.kernel.util.IllegalActionException: Error creating effigy and tableau
in .plot-error.a plot

Attempt to insert object named "plot" into container named ".configuration.directory.effigy2", which already contains an object with that name.

Re-assigning to 2.3 since this less critical.

The model consists of two Plots under PN. The error is reproducible under Ptolemy, outside of Kepler. I think it is a threading bug, where in
ptolemy/actor/lib/gui/Plotter.java, we have:
PlotEffigy plotEffigy = new PlotEffigy(containerEffigy,
containerEffigy.uniqueName("plot"));
The problem is that both plotters are trying to get a unique name for
"plot" and are getting the same name back. We need some locking here.

I'm closing this because I can't reproduce it in the current tree.
The problem is that a model with two plots was producing a stack trace.
I tried reproducing this in ptII trees from around 2010-11, but could
not reproduce the bug. However, I'm using a slow net connection for
the tests on old trees, so the problem might not be triggered.
There have been various changes to the plotter since this bug including
the splitting into interface and implementation. So, it could be
that the bug is fixed.
However, it is troubling that I can't reproduce the bug in an old ptII tree.
