Is it possible to extract a jar from a Native Image built with GraalVM?

I've built a Native Image from a Java project that includes a licensed library (jar), as a Maven dependency. That library must not be made available to anyone. Once built into the NI, is it safe ? Or is there a possibility for someone to extract the jar from the NI ?
