I found a solution.
I declared the following bean:
<bean id="classLoader" class="org.apache.aries.util.AriesFrameworkUtil"
factory-method="getClassLoader">
<argument ref="blueprintBundle" />
</bean>
And then injected it into my bean. Before the class must be loaded, I
set the Thread context classloader as follows:
if (classLoader != null) {
this.oldTccl = Thread.currentThread().getContextClassLoader();
Thread.currentThread().setContextClassLoader(classLoader);
}
try {
... load the classes with the contextclassloader ...
} finally {
if (oldTccl != null) {
Thread.currentThread().setContextClassLoader(oldTccl);
}
}
That way the class gets loaded by the bundle classloader of the
declaring bundle.
In contrary to Aries, which sets the Tccl to an instance of
org.eclipse.core.runtime.internal.adaptor.ContextFinder, the
spring-extender sets it to the declaring bundle classloader, which in my
opinion makes more sense.
