Krzysztof Barczynski updated AVRO-4036:
---------------------------------------
Description:
There is a unit test which shows what's the issue:
*
[https://github.com/krisso-rtb/avro-custom-logical-types/blob/avro-1.12.0-test-case-for-weird-equals/custom-logical-types-used/src/test/java/com/rtbhouse/custom/logical/types/SerializeDeserializeTest.java]
Most important part is block of code around line 40.
In version 1.12.0 implementation of *equals()* has been changed to
{code:java}
public boolean equals(final Object o) {
if (!(o instanceof Collection)) {
return false;
}
return GenericData.get().compare(this, o, this.getSchema()) == 0;
}
{code}
which fails when logical types are used.
More precisely: when record's field is an array of union of "null" and logical
type.
----
Basically when originalPoi and deserializedPoi are Java class instances and
{code:java}
originalPoi.getLocations().equals(deserializedPoi.getLocations()) == true {code}
then
{code:java}
deserializedPoi.getLocations().equals(originalPoi.getLocations()) {code}
should be also true but it throws an exception:
{code:java}
