> Since Jackson 2.12, serializers/deserializers for java.time.* are not enabled
> by default and need to be enabled back by adding the jackson jsr310 optional
> module.
> As the ObjectMapper instances used by json classes in the vector module do
> not include the extra jackson module, this precludes Arrow vector library to
> be used with Jackson 2.12 or higher.
> Here's an example of the error generated by Arrow when used with Jackson 2.12:
> {noformat}
> java.lang.IllegalStateException: Cannot serialize hash map to JSON string
> at
> org.apache.arrow.vector.ipc.TestJSONFile.testWriteReadComplexJSON(TestJSONFile.java:125)
> Caused by: com.fasterxml.jackson.databind.exc.InvalidDefinitionException:
> Java 8 date/time type `java.time.LocalDateTime` not supported by default: add
> Module "com.fasterxml.jackson.datatype:jackson-datatype-jsr310" to enable
> handling (through reference chain:
> org.apache.arrow.vector.util.JsonStringHashMap["timestamp"])
> at
> org.apache.arrow.vector.ipc.TestJSONFile.testWriteReadComplexJSON(TestJSONFile.java:125)
