Hi all,

This is my first post to this mailing list, :-)

I have checked out aries trunk, as explained on the website, and built it,
everything went fine.
However when i proceeded to build and run the blog sample app. I get the
following error on start up, and consequently deploying the .eba  as
explaind does not do anything.

Below is the exception when starting the osgi container.

[Framework Event Dispatcher] DEBUG org.apache.aries.blueprint -

I checked the code for class
org.apache.aries.util.tracker.AriesBundleTrackerCustomizer...But that class
is absolutely empty. In other words the .java file contains nothing, and as
a result the compiler does not generate a .class file for it, hence the
ClassNotFoundException...

By the way there are 2 more .java files in that package that are empty as
well

I am sure this was just a bad commit by somebody.

Thanx
Ivanhoe
