EnumConstantNotPresentExceptionProxy with annotations

[Sebastian Janisch]

Hey,

I am trying to get an annotation from a class like this:

SupportedTypes typesAnnotation = clazz.getAnnotation(SupportedTypes.class);

This perfectly works most of the time, sometimes however, it throws an Exception and I have no clue where this comes from:

java.lang.ArrayStoreException: sun.reflect.annotation.EnumConstantNotPresentExceptionProxy
   at sun.reflect.annotation.AnnotationParser.parseEnumArray(AnnotationParser.java:673)
   at sun.reflect.annotation.AnnotationParser.parseArray(AnnotationParser.java:462)
   at sun.reflect.annotation.AnnotationParser.parseMemberValue(AnnotationParser.java:286)
   at sun.reflect.annotation.AnnotationParser.parseAnnotation(AnnotationParser.java:222)
   at sun.reflect.annotation.AnnotationParser.parseAnnotations2(AnnotationParser.java:69)
   at sun.reflect.annotation.AnnotationParser.parseAnnotations(AnnotationParser.java:52)
   at java.lang.Class.initAnnotationsIfNecessary(Class.java:3070)
   at java.lang.Class.getAnnotation(Class.java:3029)

Please help ...

Can you show us the code for SupportedTypes? And can you also show the class header of whatever "clazz" is?

Hey,

thanks for your reply ...

the problem is fixed now ... this is what went wrong:

the annotation looks like this:

/**
 * This annotation is to be used in concert with {@link IHandler} classes to
 * declare the types of {@link Type} that the given Handler can work with.
 * <p>
 * This annotation is to be placed at the class tag of the handler and can carry
 * any number of possible types that the handler can work with.
 * 
 * @author sebastianjanisch

 */
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
@Documented
public @interface SupportedTypes
{
	Type[] value();
}

@SupportedTypes(MessageWrapper.Type.PASSENGER_BOOKING_HISTORY)

The project is a maven project and this is what the problem is. The message type enum passed to the SupportedTypes annotation is in another project. The message type got changed and maven did not rebuild the project so the compiler did not complain at the SupportedTypes annotation. hence the enum exception. It did not find the enum element specified since it was not available anymore.

Thanks for sharing the solution
