Spring will not be supported out of the box. However, the feature was developed with Spring in mind. Chris Cranford has done a "proof of concept" showing that it is indeed possible to plug Spring in as an alternative ManagedBeanFactory - he is the one who opened that Spring Jira. As he mentions in that Jira, its super trivial to plug in a Spring-based impl. In fact there are currently 2 ways this can be done : both via a setting and via a JDK "service" (aka, ServiceLoader). We will certainly help Jurgen/Spring decide a best solution if they are interested in our input.
