newbie+jedit+jswatPlugin: NullPointerException

Hopefully this is "stupid user error" :-)

New install of JEdit4.1Final + JSwatPlugin
After some hairpulling :-) ,  have successfully run through the tutorial
with the standalone JSwat 2.14.  However, unable to do anything via the
plugin.  "Show Options" & "Start VM" stop with NullPointerException; "Dock
JSwat Plugin" doesn't, but "vwStart" doesn't do anything .  AFAIK, I have
the JSwat options (Utilities > Global Options >JSwat) set, but it sure looks
like I missing something.

JEdit loaded with JSwat tutorial.
When choosing "Show Options", I get:

BeanShell error
java.lang.NullPointerException
 at javax.swing.ImageIcon.<init>(ImageIcon.java:138)
 at com.bluemarsh.jswat.plugins.jedit.JSwatPlugin.showOptions(Unknown
Source)
...
 at bsh.Reflect.invokeMethod(Unknown Source)
 at bsh.Reflect.invokeStaticMethod(Unknown Source)
 at bsh.Name.invokeMethod(Unknown Source)
... + more

At this point I know nada about BeanShell :-(, but it sure feels like I'm
missing some sort of path.  Have hit the Help & Message Boards, but I'm
still in the dark.
