Brian Stansberry commented on WFLY-3255:
----------------------------------------
I'll comment here for the record re: the rationale for the pull request James has submitted.
https://docs.jboss.org/author/display/WFLY8/Description+of+the+Management+Model specifies how the management model should be described. The "Description of an Attribute" section is most relevant, particularly the bullet point re: "value-type":
"value-type – ModelType or complex structure – Only present if type is LIST or OBJECT. If all elements in the LIST or all the values of the OBJECT type are of the same type, this will be one of the ModelType enums BIG_DECIMAL, BIG_INTEGER, BOOLEAN, BYTES, DOUBLE, INT, LONG, STRING. Otherwise, value-type will detail the structure of the attribute value, enumerating the value's fields and the type of their value."
The existing output James shows in the description of https://github.com/wildfly/wildfly/pull/6265 is incorrect per this specification, while the new output that will result from his patch is correct.
