I've met CMIS a couple of days ago, please forgive me in case the question is
naive.
I have a test case that is trying to create a document by passing the
`cmis:folder` `ObjectTypeId` (instead of `cmis:document`), and expects the test
to fail.
* With *Browser binding*, {color:#00875a}it fails with a
CmisConstraintException{color}
* With *WebService binding*, {color:#00875a}it fails with a
CmisConstraintException{color}
* With *AtomPub binding*,{color:#de350b} it creates a Folder, and then fails
later with a CmisRuntimeException{color}
While debugging the code, I've seen that *Browser binding* (along with
*WebService binding*) has a `createDocument()` method in its [ObjectService
implementation|https://github.com/apache/chemistry-opencmis/blob/trunk/chemistry-opencmis-server/chemistry-opencmis-server-bindings/src/main/java/org/apache/chemistry/opencmis/server/impl/browser/ObjectService.java#L88-L137]:

The *AtomPub Binding*, instead, has a `create()` method in its [ObjectService
implementation|https://github.com/apache/chemistry-opencmis/blob/trunk/chemistry-opencmis-server/chemistry-opencmis-server-bindings/src/main/java/org/apache/chemistry/opencmis/server/impl/atompub/ObjectService.java#L79-L158]:
!image-2021-05-18-00-06-14-967.png!
While the `createDocument()` method can check if the `ObjectTypeId` passed is
the proper one (`cmis:document`), and raise an error if an unexpected
`ObjectTypeId` is passed, the `create()` method is agnostic about the object to
create, and performs a Switch on the `ObjectTypeId` to detect the proper action
to call.
Hence, calling `createDocument()` with *AtomPub binding* and `cmis:folder`
`ObjectTypeId` will result in calling the `create()` method, and then in the
switch reading `cmis:folder` and calling the underlying `createFolder()`
method, instead of the underlying `createDocument()` one.
The folder will be created, then somewhere up in the chain[*] the error will be
detected and will trigger a CmisRuntimeException, but that implies that, for
the same test case, two different results should be expected according to the
binding used.
Could you please confirm me this is intended, and maybe shed some light on why
the *AtomPub binding* is working with a different set of methods than the other
bindings?
[*]The fact that the object constructed in the `createDocument()` method is
actually a document is checked in the [FolderImpl
class|https://github.com/apache/chemistry-opencmis/blob/trunk/chemistry-opencmis-client/chemistry-opencmis-client-impl/src/main/java/org/apache/chemistry/opencmis/client/runtime/FolderImpl.java#L83-L103]
makes me think this is the fallback for this problem, but I'd like some
confirmation here:

Thank you in advance
