Enum comma being reported as an error

I doubt that.

You might have an enum such as:

enum MyEnum {A, B,}

Is that what you have? If not, please post the exact code that is
causing the error (or if you can't, then create a new code that does)

Very specifically the following gets reported as an error

import org.junit.runner.RunWith;
import org.junit.runners.Suite;
import org.junit.runners.Suite.SuiteClasses;
 
@RunWith(Suite.class)

@SuiteClasses({
        GenericTest.class,
        OtherTest.class, // This last comma s/b legal and builds no problem in Eclipse
})

public class AllGenericTests {
}

Hi Martin,

1. This is not enum but annotation array;
2. JLS defines the following grammar for annotation array initializer -

   ElementValueArrayInitializer:
           { ElementValuesopt ,opt }

3. Moreover, there is a registered bug at Sun compiler - 6337964;
   

Conclusion: IDEA incorrectly highlights trailing comma at annotation array initializer as an error.

Please submit corresponding ticket about that to IDEA tracker.
