Classloading issue with 3.4 [message #113762]

I have a class loading problem in Eclipse RCP 3.4 I don't understand the
cause.

I have a method in ClassA located in BundleA.
This method calls a method in ClassB located in BundleB.
Some method in ClassB catches ExceptionB, located in BundleB.
The problem is that when trying to create an ClassB instance from ClassA,
I get this error:

java.lang.NoClassDefFoundError: ExceptionB

but I can do this just before new ClassB():

ExceptionB.class.toString()

Any help will be greatly appreciated

I forgot to mention that all packages from BundleB are exported.

Sorry for the noise, it was a misconfiguration.
A project had other workspace project dependencies, instead of specifiying
the dependencies as bundles.
