Tink is not compatible with protobuf-java to v4.26.0

[lily-es]

Describe the bug:

Tink is not compatible with protobuf-java v4.26.0 due to a class being renamed. Attempting to initialize Tink when using protobuf v4.26.0 results in this error

What version of Tink are you using?
1.12.0

By upgrading to protobuf-java 4.x, Tink is no longer compatible with protobuf-java 3.x. Most of the Java ecosystem is still using protobuf-java 3.x due to binary breaking changes in protobuf-java 4.x.

It seems like protobuf-java has committed to preserving backwards compatibility in order to allow consumers to upgrade, but this work is not yet complete.

protocolbuffers/protobuf#16452

protocolbuffers/protobuf#17247

Can we downgrade protobuf-java to the latest 3.x until this work is complete? Otherwise consumers will likely be prevented from taking Tink upgrades.

We released the tink-java@v1.14.1 patch release which downgrades Protobuf to 25.3.
