Running OSGi bundle prints a lot of messages and exceptions

[Eero Aaltonen]

I am going through an OSGi tutorial using Eclipse
http://www.javaworld.com/javaworld/jw-03-2008/jw-03-osgi1.html?page=3

Executing the "Hello World" bundle results in a large amount of messages and exceptions.

Now I also have errors on eclipse startup.

I tried starting with
eclipse -clean -clearPersistedState

but even that doesn't work.

sigh..

Nuke (delete) yourWorkspace/.metadata/.plugins

Restore all projects, perspectives, etc by hand.

I say it was far too easy to break the IDE with default settings.

What originally happened: "I wanted to run Hello World bundle in OGSi environment in Eclipse"

In Run->'Run Configurations'->"New Launch Configurations"

everything is selected by default. I think this is a poor default, since it breaks the IDE (or well, parts of it).
