Do you perhaps have the interface HelloBean in both bundles? If yes then
you should extract it to a separate interface bundle.

If you reference the service with a filter then OSGi will inject
the correct impl object. You will not even need to have a dynamic
import as the impl is installed by the bundle1.
So this should simply work. What exception do you get?

Bundle 1 and Bundle 2 contain a different implementation of the
interface which is exposed as OSGI service
Bundle 1
<bean id="service"
class="com.mycompany.poc.service.impl.FeedbackTeamWS"/>
<service ref="service"
interface="com.mycompany.poc.service.Feedback">
<service-properties>
<entry key="version" value="1"/>
</service-properties>
</service>
Bundle 2
<bean id="service"
class="com. mycompany.poc.service.impl.FeedbackTeamDB"/>
<service ref="service"
interface="com.mycompany.poc.service.Feedback">
<service-properties>
<entry key="version" value="2"/>
</service-properties>
</service>
So the bundle C do an OSGI lookup to retrieve using as key the
interface name "com.mycompany.poc.service.Feedback", the class
implemented in bundle 1 or bundle 2.
What would be great is that the bundle C when the following bean
is instantiated loads the class from the bundle 1 as the filter
of the reference to be found corresponds to it
<property name="feedbackService">
<reference interface="com.mycompany.poc.service.Feedback"
filter="(version=1)"/>
</property>
Intrinsically we know that the class implementing this interface
belongs to bundle 1 as filter = 1 = OSGI service exposed by
bundle 1 = class = com.mycompany.poc.service.impl.FeedbackTeamWS
