Why is this code not compiled in javac, but there are no errors in eclipse?

The following codes:

@Retention(RetentionPolicy.RUNTIME)
@Target( { ElementType.METHOD,ElementType.FIELD,ElementType.ANNOTATION_TYPE })
@Constraint(validatedBy = {
        MinTimeIntCoConstraintValidator.class,MinTimeIntCoListConstraintValidator.class,MinTimeDoubleCoConstraintValidator.class,MinTimeDoubleCoListConstraintValidator.class,})
@Documented
public @interface MinTimeValueCo
{
    int value();
    String message() default "value does not match minimum requirements";
    Class<?>[] groups() default { };
    Class<? extends Payload>[] payload() default {};
}

Compiled in eclipse but not in sun / Oracle compiler:

> MinTimeValueCo.java:19: illegal start of expression
>     [javac]       })
>     [javac]       ^
>     [javac] 1 error

This is because mintimedoublecolistconstraintvalidator Comma after class

It works when I delete commas:

@Constraint(validatedBy = {
        MinTimeIntCoConstraintValidator.class,MinTimeDoubleCoListConstraintValidator.class
        })

I use JDK 1.6 0.10. Do you know why this is illegal and compiled in eclipse?

Solution

This is an error in javac of Java 6 There are 07000 in some places, the eclipse compiler follows the standard here, and Java 6 never allows trailing commas anywhere

You can try to compile the code using javac in Java 7 with the option - source 6 - target 6 (to get Java 6 compatible bytecode) If the error persists, file it It may be repaired
