Does LiteRT-LM require Java 21?

Does com.google.ai.edge.litertlm:litertlm-android support Java 17?

My build environment must use Java 17, but when I add litertlm-android (version 0.10.0), I get the following error indicating that the dependency was compiled with Java 21:
—————————–
error: cannot access Message
import com.google.ai.edge.litertlm.Message;
^
bad class file: ~/.gradle/caches/…/litertlm-android-0.10.0-api.jar(/com/google/ai/edge/litertlm/Message.class)
class file has wrong version 65.0, should be 61.0
Please remove or make sure it appears in the correct subdirectory of the classpath.
——————————

Class file version 65.0 = Java 21, while 61.0 = Java 17, so it looks like the library is built with a newer JDK than my project can use.

However, the Google AI Edge Gallery sample app appears to work with Java 11, which makes me wonder whether my Android project is misconfigured or if LiteRT‑LM truly requires Java 21.

Is this a configuration issue on my side, or does LiteRT‑LM actually require Java 21?
