Before Change

      // For rewriting JDK classes to work, the JAR file has to be listed specifically in
      // the JAR manifest as something that goes in the bootclasspath.
      // The MANIFEST list a jar "allocation.jar" this is why we have to rename it
      agent_jar = os.readlink(profile_classpath(self.agent_profile)[0])
      allocation_jar = os.path.join(os.path.dirname(agent_jar), "allocation.jar")
      // TODO(Steve Gury): Find a solution to avoid copying the jar every run and being resilient
      // to version upgrade
      shutil.copyfile(agent_jar, allocation_jar)
      os.environ["ALLOCATION_JAR"] = str(allocation_jar)
