#4 Plugin crashes when you select its menu item

[Martin McCallion]

jEdit 4.3pre16 using Java 1.6.0_11; Xilize plugin version 3.0.3.31

When you pull down the Plugins menu and select the Xilize option, you get a BeanShell error, as shown below. I'm sure I had this working in one version of jEdit, maybe a year or two ago, but this is the current state.

I can't find any references to this online. I'm a programmer, but I haven't got time to learn all about jEdit plugins just now. It looks like there's no implementation for the Exec.StateChangeListener interface, though.

Here's the stack trace:

I can replicate this.
