I found the Gathering Information About Your Plug-in page.
On windows you have to start eclipse with java.exe (instead of javaw.exe) in odrer to ge a console window. Therefore, add
-vm C:\YOURVMPATH\bin\java.exetho the eclipse start command (or shortcut). To get the OSGI console
-consolas startup parameter.
Now to see all plugins (and the state of the plugins) simply type
ssinto the console. To get a stracktrace of all threads hit ctrl-break in the console window (I had a hard time finding the break key on my keyboard. it's the top right key on my keyboard)
