exception trying to access to referenced service in destroy-method

[KcTang]

Hi,

i've got a working blueprint bundle to register some default OBR
repositories on initialization of the bundle.

The xml config looks like:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";>

    <bean class="play.osgi.bundle.config.RepositoryRegistrationBean"
          init-method="init" destroy-method="shutdown">
        <argument index="0" ref="blueprintBundleContext"/>
        <argument index="1" ref="repositoryAdmin"/>
    </bean>

    <reference id="repositoryAdmin"

interface="org.apache.felix.bundlerepository.RepositoryAdmin">
    </reference>

</blueprint>

Both BundleContext & RepositoryAdmin are injected to
RepositoryRegistrationBean's constructor. The init() works.

However, when i try to access the RepositoryAdmin during shutdown(), i got
this exception:

Does it mean that we cannot access referenced services in destroy-method?
Any place I can read up on these?

A slightly unrelated question....how come INFO log is used instead of ERROR
log?
