Make `JsonNode` implicitly create `ArrayNode`s for repeated XML Elements

[cowtowncoder]

(note: requires FasterXML/jackson-databind#2732 to be implemented first)

One of long-standing issues with this module is that JsonNode does not work well with relatively common XML case where there are sequences of elements with same name: this is typically used to present Arrays, for example.
By default JsonNode assumes uniqueness of property names, and this leads to either loss of all but one element (first or last, depending), or exception for duplicate entries.

It should be easy enough to make JsonNodeDeserializer have logic of "auto-converting" value nodes into ArrayNodes, in case of "duplicates", however; and as long as this is guarded with something (for example, new StreamReadCapability.DUPLICATE_PROPERTIES), it should be completely safe and not change regular JSON processing accidentally.

@cowtowncoder I'm facing this issue. Is there any work around for this before 2.12? Please help.

[Jearkrishna]

@cowtowncoder at present it is only recognising last found element if there are not inorder. Do we have any work around for this ? Otherwise I'm unsure what else to do other than switching other parser.

Appreciate your help.

Nope, I don't think this can really be worked around with earlier versions.
You could perhaps implement your own POJOs to get something similar by overriding set methods, but that's about it.

Okay. Thanks for the respinse.for now, I went ahead with JAXB. May be will switch back to Jackson once new version released. 👍
