I finally came to my senses and debugged the problem by myself. It turned out that org/apache/activemq/util/TypeConversionSupport has a hard dependency on hawtbuf, which means this class cannot be initialized if hawtbuf is not present (which was not a problem before). Unfortunately the problem occured in IntrospectionSupport.setProperty which does not log exceptions (for a usually good reason, though).
Because of that, I suggest not putting hawtbuf into extra/, since that suggests that it is optional, while it is not really.
