FYI: com.fasterxml.jackson > 2.14.2 will fail

Just FYI. I'm trying to use zarr-java for the omero-zarr-pixel-buffer. This pulls in (via amazon-s3-sdk) com.fasterxml.jackson libs 2.15, which will give this error when trying to read an array:

Exception in thread "main" java.lang.NoSuchFieldError: READ_UNKNOWN_ENUM_VALUES_USING_DEFAULT_VALUE

Forcing 2.14.2 works for now.

From experience working with jackson libraries, compatibility between the core library and the extension modules is only guaranteed when using the same minor version - see https://github.com/FasterXML/jackson/wiki/Jackson-Releases#general

zarr-java/pom.xml

Lines 76 to 85 in e758d54

	<dependency>
	<groupId>com.fasterxml.jackson.core</groupId>
	<artifactId>jackson-databind</artifactId>
	<version>${jackson.version}</version>
	</dependency>
	<dependency>
	<groupId>com.fasterxml.jackson.datatype</groupId>
	<artifactId>jackson-datatype-jdk8</artifactId>
	<version>${jackson.version}</version>
	</dependency>

For downstream libraries using a different minor version of the libraries, there are two possible options:

• either forcing jackson-databind:2.14.2 as described in the issue
• or if requirements like aws-sdk-java depend on jackson-databing:2.15.0, also declare jackson-datatype-jdk8:2.15.0

Thanks for the hint!
Do you think we should update the jackson version to a more recent one? @sbesson

Edit: Never mind. I missed #26.

Latest version 2.20 seems to work. I just got this issue when 2.15 was pulled in from another dependency. So hopefully updating everything will solve the problem.
