Lambda the Ultimate

As I understand, quite a few of usual LtU readers do Java programming on a daily basis.
JBoss Seam (not Seam VM) seems quite popular lately (more than for a year already) in Java "enterprisish" community.

Could we try and critisise Seam from PLT point of view? Can it be considered a PL? If yes, of what paradigm? Is it a DSL? What existing formalisms can be used to model Seam? What conclusions will follow (unsaveable, perfect, needs this and that changes to become more uniform/consistent)?
