More fun with substitution tests
Fixed OSGI feature verification issues, but crappy

    Probably want to implement a different
    selector language than json path.

    Json-Path bundle specifies json-smart
    as mandatory dependency but it has no
    metadata.

    Embedding brings in a tower of dependencies!

    Maybe JXPath?

    If JXPath is expressive enough it might
    allow less unecessary conversions to and
    from JSON.
