Oracle said OpenJDK does not accept code generated by generative AI tools, citing unresolved legal and provenance issues around authorship, ownership, and compliance with the project’s contribution requirements. The project requires contributors to certify that submitted code is their own work or that they have the necessary rights to provide it, and Oracle said AI-produced output makes those assurances difficult because the origin of training data and the resulting copyright status may be unclear.
The policy, published as an interim legal position by OpenJDK, reflects broader concern in open-source development over whether AI-assisted patches can satisfy licensing and attribution obligations. Reporting on the issue also pointed to similar resistance in other projects, including NetworkManager, where maintainers reportedly rejected AI-generated patches because uncertain copyright provenance could conflict with the project’s LGPLv2.1 licensing requirements.

OpenJDK published an interim policy stating that AI-generated code contributions are not accepted because contributors must be able to certify authorship, rights, and provenance, and generative AI creates unresolved legal and licensing uncertainty.
