Troubles with class loading with jsr 303.
I have a pax-exam test of code that uses Apache bval and thus
javax.validation, and I use the servicemix spec provider.
The test fails with java.lang.ClassCastException:
org.apache.bval.jsr.ApacheValidationProvider cannot be cast to
javax.validation.spi.ValidationProvider.
When I stop it in the debugger, I see that there are indeed two Class
objects afloat for ValidationProvider.
One of them is a sun.misc.Launcher$AppClassLoader. The other is an
OSGi class loader.
The sun.misc one is the one for the interface of the class returned by ...
Class<? extends ValidationProvider> providerClass =
org.apache.servicemix.specs.locator.OsgiLocator.locate(ValidationProvider.class);

You may use javax.validation.ValidationProvider class directly to lookup spec implementation, if you have geronimo-osgi-locator bundle installed. Geronimo locator is installed by default in karaf. I was using bval a lot in our tests. You can check this repo - it does work with karaf 3.0.4, but 2.x is pretty much the same:

I had to set the context class loader.
