The only JavaScript offering from Oracle that I know of is GraalVM[0]. It's funny though - they use "JavaScript" and "ECMAScript" interchangeably in their docs. They call it "A high-performance embeddable JavaScript runtime for Java" but then tout it as "ECMAScript Compliant", basically acknowledging that JavaScript is defined by ECMAScript specs and the terms mean the same thing.
Them calling it ECMAScript in some instances means that it follows the actual ECMA spec for ECMAScript (what everyone calls JavaScript historically). Them calling it JavaScript implies it could be their flavor, or something like Node and not necessarily strictly ECMAScript, at least that'd be the reason I'd use it interchangeably.
