Hi,
So first it was an iPOJO issue
(https://issues.apache.org/jira/browse/FELIX-2664). I've fixed it in the trunk.
To check, compile the manipulator form the iPOJO trunk and configure the
maven-ipojo-plugin with:
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-ipojo-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>ipojo-bundle</goal>
</goals>
</execution>
</executions>
<dependencies>
<dependency>
<artifactId>org.apache.felix.ipojo.manipulator</artifactId>
<groupId>org.apache.felix</groupId>
<version>1.7.0-SNAPSHOT</version>
</dependency>
</dependencies>
</plugin>
Regards,
Clement
