 Description   

BundleContextBackedModuleFactoriesResolver getAllFactories will find two conflicting factories with the name 'pcep-session-proposal-factory-stateful02'.

I detected this on a copy of the ServiceProvider distribution 0.1.2-SNAPSHOT. My application does not export a copy of this factory into the environment. Any suggestions on tracking down the source of the second factory in the controller environment - there should only be one.

I'm working on a set of steps to reproduce that will not require my application (too many extraneous bits). I'll update this bug report when I have the steps available.

Further investigation note:

When two instances of org.opendaylight.bgpcep.pcep-ietf-stateful02 are found, the OSGi webconsole only reports the one instance::

Service 380 - [org.opendaylight.protocol.pcep.PCEPSessionProposalFactory] (pid: n/a)
from Bundle 91 - org.opendaylight.bgpcep.pcep-ietf-stateful02 (org.opendaylight.bgpcep.pcep-ietf-stateful02), version 0.3.1.SNAPSHOT
instanceName: stateful02-prop
implementationName: pcep-session-proposal-factory-stateful02

The error appeared to have been caused by not setting its dependency on pcep-ietf-stateful02 to provided. When its not set to provided a second instance will be created, causing the problem.

<dependency>
<groupId>org.opendaylight.bgpcep</groupId>
<artifactId>pcep-ietf-stateful02</artifactId>
<version>0.3.1-SNAPSHOT</version>
<scope>provided</scope>
</dependency>

I've marked this issue as resolved invalid as we can work around the issue by marking the dependency as provided in the container.

We will note however, that the module name is hardcoded as such multiple copies can not exist - Not sure if this would be considered a bug or not.
