Not based on licensing. There is no licensing barrier to making an runtime with the same semantics as ART or Dalvik that runs Java bytecode and is fully compatible with Oracle Java.
Also not by intent. Dalvik bytecode was designed for running without a JIT compiler in a battery powered device - a very specialized and critical design goal.
Oracle is the party that's playing games with standards and licensing, intentionally keeping openness and licensing requirements opaque and intentionally vague. I know this firsthand.
