Consider this code:
private static <T extends Byte> byte test(T test) {
if (test instanceof byte i) { return i; }
return 2;
}
public static void main(String argv[]) {
System.out.println(test(Byte.MAX_VALUE));
}
An exception has occurred in the compiler (23-ea). Please file a bug against the Java compiler via the Java bug reporting page (https://bugreport.java.com) after checking the Bug Database (https://bugs.java.com) for duplicates. Include your program, the following diagnostic, and the parameters passed to the Java compiler in your report. Thank you.
