Summary: After Undo Comment: "IllegalArgumentException: At end"

Initial Comment:
When I start DrJava, and enter in the empty document

/**

and hit return, the text changes to

/**
 * 

Then I hit "Undo", and I get the following exception.
>From that point on, DrJava is in an unstable state, and
it can't even be quit without throwing more exceptions
that prevent closing it.
