Problem is, like any third party product we are not in control of the spring code, and we just don't know whether it is doing illegal operations or not. At some point we should probably test JBM with Spring, and then if we are happy, it could become a supported configuration. I'm not saying it doesn't work with JBM, it's just that we simply don't know and if we were to make promises to our customers based on a guess that would be irresponsible of us.
