JDK-8285932 - Implementation of JEP 430 String Templates (Preview)
Description
Code:

public class Demo {
    public static void main(String[] args) {
        System.out.println(STR.'\{1+2}');
    }
}

Latest javac (build 22-ea+7-489) compiles this and produces 3 as an
output. I believe this is a mistake in the compiler.
