Hi,
I am working on a RCP application for quite a while now and have run
into the same problem several times now. What is the reason for using
these anoying try-finally blocks without even one catch? This is realy
anoying when debuging an application. There seems to be no way of
finding the reason for an exception if it is simply thrown away. At the
moment I step through the entire code seting breakpoints at the current
position and removing the ones bevore. This is sort of
Mointain-Climbing-Debugging and it realy suxx.
Is there any way to debug a plugin in a more professional way?

There are many good reasons to do so. What's bad are empty catch blocks.

Simply tell the Debugger to stop when an given exception occurs. If you
don't know which one it is start with the most specific you suspect
(e.g. exceptionally).

Sorry for the late reply, but I was sick this week :(
Unfortunately I didn't write up the exact locations, but I found try
blocks with finally without any chatch all over the place.

Well how about a log-output of type debug? Since Eclipse is not a
finished Product I think this could help a lot of development problems.

The code abnormally exits in the middle of the try block, then the finally block is executed (often doing some kind of cleanup), then the exception is propagated outwards as normal. It doesn't affect anything that may be expecting an exception; it will still be reported.
Hmmm ... that was what I first thought too. Unfortunately I step through
the eclipse code and suddenly I jump into the finally block and after
that no Exception is to be found anymore. Where has it gone?
