             Summary: Regression after ARIES-1342: Duplicate interface name in 
class file
                 Key: ARIES-1618
                 URL: https://issues.apache.org/jira/browse/ARIES-1618
             Project: Aries
          Issue Type: Bug
          Components: Proxy
    Affects Versions: proxy-impl-1.0.5
         Environment: Karaf 4.0.6, JDK 1.8.0_u77
            Reporter: Vladimir Konkov


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

{code:xml}
<?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>
{code}

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:
{noformat}
Caused by: org.apache.aries.proxy.UnableToProxyException: 
java.lang.ClassFormatError: Duplicate interface name in class file
