Diagnostics being swallowed - how to see details? [message #52425]

I'm writing an editor.
It initialises OK (gets to the end of the init() method), but when I
open a document, it displays on the console:

Unhandled event loop exception
Reason:
Failed to execute runnable (java.lang.NoClassDefFoundError)

There is no stack trace, so I can't tell where it is having problems.

Is there any way of suppressing/changing the Eclipse error handling so
I can see the entire exception?
Or is there some other suitable debugging technique to solve such problems?

Many thanks,
Benedict

You can try adding a java Exception Breakpoint. In the Breakpoint view
click on the exclamation mark icon that has the J beside it, and then
select the Exception you want to break at.

Have you looked in the .log file in the .metadata directory of your
runtime workbench. This should contain the stack trace associated with
the exception.
