Hybris rule engine not invokes promotions

When we want to invoke a promotion in clustered environment, we get an exception. It looks like a maven dependency problem with wrong protobuf-java library version. But we couldn't find a solution to fix.

Similar problem:

When making ant production, the order of extensions is created changing. There are two Protobuf jars, for solr and ruleengine. Solr based protbuf version is 2.5 and there is problem with rule engine.

Possible solution is replace the localextions.xml generated after "ant production" with the original one. Then, start server successfully.
