Description
The following test fails
assertThat(read("{\"_links\":[]}",ResourceSupport.class).getLinks().size()).isEqualTo(0);
the issue could be solved the following way
if (!JsonToken.FIELD_NAME.equals(jp.getCurrentToken())) {
if(result.isEmpty() && JsonToken.END_ARRAY.equals(jp.getCurrentToken())){
continue;
}
throw new JsonParseException(jp, "Expected relation name");

Research direction
Start with the failing read("{"_links":[]}", ResourceSupport.class) test and locate the JSON link deserialization path. Check the parser's handling of the current token for an empty _links array, then verify that the test passes without breaking non-empty link parsing.
