> Part of my plugin includes a .java file that contains an annotation type declaration.  It looks like this:
> {quote}
> package org.jboss.lang.annotation;
> import java.lang.annotation.ElementType;
> import java.lang.annotation.Retention;
> import java.lang.annotation.RetentionPolicy;
> import java.lang.annotation.Target;
> @Retention(RetentionPolicy.RUNTIME)
> @Target(ElementType.ANNOTATION_TYPE)
> public @interface Inherited {
> }
> {quote}
> When the JavaMojoDescriptorExtractor encounters this file it crashes because of an ArrayIndexOutOfBoundsException.  Because the code is trying to access the 1st element of a zero length array.  The attached file has a simple fix where the descriptor extractor just ignores any java source file that does not contain a valid class.
