See e.g.

    "defaultValue": "none",
    "allowableValues": {
        "valueType": "LIST",
        "values": [
            "none",
            "any",
            "*",
            "#"
        ]
    }

Issues:

• How do we get a meaningful, short Enum name
• If the Enum is null, the parameter is not added
• The Enum name could be not a valid Java name. For example, TerminateOn.none is valid (though t might be better uppercased) while TerminateOn.# is not (so we must rename it to TerminateOn.POUND)
