Description

I have regression on Karaf 4.0.6 (Proxy Service 1.0.5) with such blueprint config:

<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0">
   <reference id="transactionManager" interface="org.apache.aries.transaction.AriesTransactionManager"/>

<!-- other bean defenitions -->

</blueprint>

Because of hierarchy ordering fix in ARIES-1342 resulting interfaces set contains duplicates - two javax.transaction.TransactionManager entries. As result Exception thrown on proxy class generation:
