🦉 Allocation of Resources Without Limits or Throttling

[chrislin22]

This upgrade contains a significant breaking change in version 1.12.1 that affects the deserialization of logical types. Code that previously worked may now fail with a ClassCastException.

Breaking Change: Logical Type Deserialization

In Avro 1.12.1, a change was introduced (AVRO-3989) that causes logical types to deserialize to their corresponding rich Java types instead of their underlying primitive types when using GenericRecord. [10]

For example:

• timestamp-millis now deserializes to java.time.Instant instead of Long.
• date now deserializes to java.time.LocalDate instead of Integer.
• uuid now deserializes to java.util.UUID instead of String.

This will break any code that casts the result of genericRecord.get("field") to the primitive type. [10]

Other Notable Changes

• Fastread by Default: In version 1.12.1, the "fastread" feature is enabled by default, which could alter performance characteristics. [1]
• Security Fixes: Version 1.12.1 includes several security fixes for the Java SDK, including the deprecation of a property related to serializable classes in favor of org.apache.avro.SERIALIZABLE_CLASSES. [1]

Recommendation:
This is a high-risk upgrade. Before merging, you must carefully audit all code that reads Avro data, especially if using logical types. Update any casting to expect the new, richer Java types (e.g., Instant, LocalDate) to avoid runtime ClassCastException errors. [10]
