[ jEdit-users ] Problems with jDiff 1.3.2 in jEdit 4.2pre6

[David B. <bu...@ed...>]

List,
    I keep getting a beanshell error when trying to use the jDiff plugin.
I'm running on Win2K, jEdit 4.2pre6 and just installed jDiff 1.3.2
I have my view split between the two files I want to diff and then I select
Plugins->jDiff->Dual diff and then I get this error.

Known issues?
How would I debug?

The Error:

java.lang.NullPointerException
