OSGi_R4.core.pdf -> 3.4 Class Loading Architecture defines the "class
space".
It further points out:
"A class space must be consistent, such that it never contains two classes
with the same fully qualified name (to prevent Class Cast Exceptions). "
I have tested this with a simple example Plugin A, B and C.
B and C exports the same class in the same package. A creates a dependency
to B and C.
It perfectly runs at least with my eclipse 3.1.0 installation.
It also fits the deep first search, if B requires C the class from C is
loaded.
Is this a defined behaviour for equinox or is there any strict mode that
avoids this feature ?

This is expected behaviour. Is it causing you a problem?

it does not cause a problem if it is known.
But it does not reflect the osgi standard in reflect to the "consistency of
the class space" ?

Might be best to enter a bug report in the Eclipse/Equinox bugzilla with
some example code. I'm not quite seeing the problem.
