They don&#x27;t even have to go through those motions, they could just release what they have under the same license as OpenJDK and grab some of the interface definitions they need from OpenJDK<p>And they wouldn&#x27;t necessarily be &quot;legally in the clear&quot;... when this is all said and done they may be found to have infringed copyright illegally and will have to pay a price for breaking the law.
