---------------------------------
Summary: [Java] Ensure tests don't change the default global
fastread behaviour
Key: AVRO-4326
URL: https://issues.apache.org/jira/browse/AVRO-4326
Project: Apache Avro
Issue Type: Bug
Reporter: Ryan Skraba
Using the invoker, we run the java tests twice, once with
{{org.apache.avro.fastread}} set to true and once with it set to false.
Some tests explicitly change this setting via
{{{}GenericData.setFastReaderEnabled(){}}}, which is fine if they are using a
new instance of SpecificData or GenericData. If they change the singleton
instance that tests use by default, it might affect other tests inadvertently.
[https://github.com/apache/avro/pull/3924] fixed one example where the fast
reader was changed on the global singleton, but we should find a strategy to
make sure tests that use setFastReaderEnabled only affect their isolated
instances.
