Oracle has banned AI-generated code from OpenJDK contributions, citing safety, security, and intellectual property risks. The open-source Java project steward said developers can use LLMs privately for debugging and reviewing code but cannot submit AI-generated material to repositories, pull requests, or other project channels. The policy contrasts sharply with Oracle's internal practices. Co-founder Larry Ellison recently declared that AI models now write Oracle's code, whilst co-CEO Mike Sicilia credited AI tools with enabling smaller engineering teams to deliver faster. Oracle is investing $70 billion this year in datacentre expansion. The spending spree prompted credit agency S&P to downgrade Oracle's rating to BBB-, one notch above junk status, citing uncertain returns on investment.
