Oracle bans AI-generated code from OpenJDK

Oracle has banned AI-generated code from OpenJDK, the open-source reference implementation of Java that Oracle stewards. The report sets the policy directly against Larry Ellison's public claim that Oracle isn't writing its own code anymore — one standard for the company's internal engineering, another for the codebase it accepts patches into from the outside.

#Why it matters

OpenJDK is one of the more consequential test cases for the question every large open-source project is now working through: whether model-generated contributions carry enough provenance risk to be worth refusing outright. A ban at the JDK level is a heavier signal than one at a hobby project, and it comes from a vendor whose CEO is simultaneously selling AI-written code as the future.

The underlying policy text and its enforcement mechanics haven't been detailed in the coverage so far — the 134-comment Hacker News thread is currently doing most of the interpreting.
