json-annotation | quickest way to add a JSON format | JSON Processing library

Jackson annotations applied to POJOs exported through an OSGi depdendency does not work when the POJO is serialized in an importing bundle at Runtime. If the POJO is placed in the using bundle directly, or tested in a Unit Test (in either bundle), everything works as expected.

Does anyone know what could make the runtime serialization ignore the Jackson-annotations at runtime in the importing OSGi-bundle?

This is a looong question. I have tried to create an as simple example as possible. If anything is unclear, please let me know, and I will try to elaborate.

Let's assume we have want to serialize a simple POJO exported and imported over OSGi. The JSON-annotations should work both in the importing and exporting bundle, both runtime and during unit tests (runtime fails in the when imported).

Both runtime and unit tests of the Jackson serialization works just fine in the bundle where the POJO itself is declared.

POJO to serialize

The @JsonProperty-annotation should make any serialized version of this POJO look something like {"correctSerializedName":"someName"} and not {"javaName":"someName"}:
