In which one?

yep, I'm using Eclipse 3.1 and the class-dir points to the porject's
output directory.
Well, I came across this problem when I wanted to use a generator but I don't
think this problem is related to generators in general.
Maybe you can try out
http://people.apache.org/~reinhard/rcl/Ccooon%20ReloadingClassloaderTest.zip
which contains a ready to use Eclipse project and an html generator that
produces my problem. I hope this error is reproducible by others :-/

Problem with ReloadingClassLoader
I have a nasty error that I can't track down. I'm using the ReloadingClassloader
of trunk and include it with following code:
I declare a couple of components like generators and actions. Using an action
works as it has been doing for months but since an upgrade to the latest SVN I
get following error when declaring a custom generator:
The HTTP response is:
HTTP ERROR: 500 my.CustomGenerator (Bad index in constant pool.)
At the console following stacktrace appears:
java.lang.ClassFormatError: my.CustomGenerator (Bad ind
ex in constant pool.)
at java.lang.ClassLoader.defineClass0(Native Method)
at java.lang.ClassLoader.defineClass(ClassLoader.java:539)
at java.lang.ClassLoader.defineClass(ClassLoader.java:448)
at org.apache.cocoon.components.classloader.ReloadingClassLoaderFactory$
DefaultClassLoader.fastFindClass(ReloadingClassLoaderFactory.java:182)
Any ideas?
BTW, currently ReloadingClassLoaderFactory doesn't work out of the box as it
isn't declared in any xconf and also requires commons-io which is optional.
