---------------------------------
Summary: Extention proxy-method="classes" caused
UnableToProxyException
Key: ARIES-932
URL: https://issues.apache.org/jira/browse/ARIES-932
Project: Aries
Issue Type: Bug
Components: Blueprint, Proxy
Environment: Karaf 2.3.0 with ASM 4.0 and Aries 1.0.0
Reporter: Roman Minko
UnableToProxyException arises with Karaf 2.3.0/Aries 1.0.0 when install a
blueprint based bundle into container.
Caused by: org.apache.aries.proxy.UnableToProxyException: The class
xxx.xxx.SomeClass is not an interface and therefore a proxy cannot be generated.

The blueprint configuration in the bundle:
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";>
...
<reference
xmlns:ext="http://aries.apache.org/blueprint/xmlns/blueprint-ext/v1.0.0";
ext:proxy-method="classes" id="SomeFeature" interface="xxx.xxx.SomeClass"/>
...
</blueprint>
The stack shows that the JDK proxy (JdkProxyManager) used instead of
AsmProxyManager,
even though ASM 4.0 installed in container:
