I have tried to build the current version of ServiceMix 5. The compilation of ServiceMix fails with error about missing dependency spring-asm in version 3.2.4.RELEASE. It is caused by spring-asm in dependencyManagement in the main pom. spring-asm has been removed with Spring 3.2.x (http://docs.spring.io/spring/docs/3.2.x/spring-framework-reference/html/migration-3.2.html D.3).
After this problem is fixed there is another problem with installing examples in itests. The example features still refer the original spring jars which are no more osgified with Spring 3.2.x. The jars from EBR should be used.
