Oracle bans AI-generated code from OpenJDK

Oracle has banned AI-generated code from OpenJDK contributions due to concerns about safety, security, and intellectual property, while developers can use AI tools privately for debugging and code review. This policy contradicts Oracle's own internal operations, where co-founder Larry Ellison stated that AI models now write much of Oracle's code. The contradiction has drawn attention as Oracle simultaneously invests $70 billion in datacentre expansion, leading S&P to downgrade the company's credit rating to BBB-.
