No I don't know how to fix it. I was hoping that I wasn't the first person
in the world to write an appender for an Ecipse plug-in and that someone
might have worked it out already :)

Subject: Re: [logback-user] RCP
Anyway, even without the stack trace, we can assume that your custom
appender will be instantiated by calling the
instantiateByClassName(String, Class, Context) method in OptionHelper
(line 36). This method assumes that you want to use the class loader
which loaded the current logback context to be used. (This is usually
the same class loader that loaded all other logback classes as well.)
Thus, you have to make sure that the said class loader can load
foo.RCPAppender. Can you do that?
