Upgrade libraries to Java 21

HI there,
Is there a plan in the core, util, abi libraries to upgrage the Java version to 21? P I ask because springboot will end support for the version supporting java 1.8 in a few months.

good idea.
currently,tron community are disscussing about upgrading the java-tron JDK version to a newer version(eg:jdk 17/jdk 21), not been decided yet.check it here
also,in my opinion, trident-sdk is a java SDK of java-tron, which means it should keep updated with java-tron including the jdk compability.
btw, you can introduce your idea in that issue where community members dissussed.
