Description

Currently this code:

import java.lang.annotation.*

@Retention(RetentionPolicy.RUNTIME)
@Target([ElementType.TYPE, ElementType.METHOD])
public @interface Foo {
    int i() default 3
    short s() default 3
    byte b() default 3
    char c1() default 65
    char c2() default 'A'
    char c3() default (char)'A'
}

generates compile time errors such as these:

6 compilation errors:

Attribute 's' should have type 'java.lang.Short'; but found type 'int' in @Foo
 at line: 7, column: 23

Attribute 'b' should have type 'java.lang.Byte'; but found type 'int' in @Foo
 at line: 8, column: 22

Attribute 'c1' should have type 'java.lang.Character'; but found type 'int' in @Foo
 at line: 9, column: 23

Attribute 'c2' should have type 'java.lang.Character'; but found type 'java.lang.String' in @Foo
 at line: 10, column: 23

expected '(char) A' to be an inline constant of type char in @Foo
 at line: 11, column: 23

Attribute 'c3' should have type 'java.lang.Character'; but found type 'java.lang.Object' in @Foo
 at line: -1, column: -1
