I've installed the Line coverage plugin. When the test is launched, I'm
getting an exception shortly after the new workbench window is displayed. I
don't see any of my code on the stack trace, so I'm not sure what is going
wrong.

Environment:
Eclipse 3.2
WTP 1.5

Shown below:
1. stack trace
2. java code that launches the test (sorry about the lack of indents)

Is this supposed to work?
Any suggestions?
Does this need a bug report?

BTW, I saw some other messages that mentioned issues w/ JDK 5.0, but I'm
developing plugins that target and take advantage of JDK 5.0 features, so it
wont be easy (if at all possible) to try w/ JDK 1.4.
