We now use the current request's URI as base link for all links created for a collection resource. This especially has effect in the creation of pagination links as we now carry potentially applied critierias (induced by our Querydsl based filtering support) forward to the navigation links generated.
Moved off Spring Framework deprecations for HttpMessageNotReadableException. This required some rearrangements of method signatures for types (hopefully) exclusively used by internal abstractions (some public, but not very friendly for user extension in the first place).
Switched to consistent use of Pageable.unpaged() instead of null. Switched to the use of new factory methods in Spring HATEOAS. Some Java 8 based improvements in request handling to simplify the implementation code. Deprecation of code that got obsolete due to the use of the factory methods.
Moved off some deprecations in Jackson APIs.
Removed a couple of unused imports. General avoidance of common warnings. Suppression where needed. Removed dead code in configuration.
When merging new data into a PersistentEntity, JsonNodes of array types were deserialized into immutable Lists, but the list is later mutated if the source and target arrays are of different sizes. This commit ensures that an array is deserialized into a mutable list.
Original pull request: #371.
The usage of text/uri-list as media type was entirely broken and not even advertised in the reference docs anymore. It's now again supported for both to-one and to-many associations via Collections. Maps are rejected as they cannot be rendered as list of URIs correctly. Updated reference documentation accordingly.
Added a custom MapModel implementation of RepresentationModel as apparently using Maps with EntityModel does not unwrap the content properly due to [0].
