Build Agent Language Level Support

The LanguageLevel class in jps doesn't support anything above Java 13 in the build agents which results in this error for my project which is trying to use Java 15.

java.lang.IllegalArgumentException: No enum constant org.jetbrains.jps.model.java.LanguageLevel.JDK_15

Idea however supports unto Java17 at this moment.

When will the build agents be updated to support newer version of java?
