Currently it is not possible to get annotations from declared entities in Guvnor. It seems to be related to this jira: https://issues.jboss.org/browse/JBRULES-2792

_______________________________________________________________________________
    All types created or enhanced by a DRL declare construct must be retrievable from the KnowledgeBase using
    Declare getDeclare( String pkg, String name )
    A Declare object must provide getters String getPackageName(), getName(), Map<String,Object> getMetaData() (same as Rule)
    A Declare object must provide Class<?> getFactClass() returning the created or enhanced java-lang.Class.
    A Declare object must provide long getInferredExpires() returning (for @role(event)) the inferred expiration offset or -1 if none.
