> I have an {{AnnotationCollector}} that refers to some Java classes (type converters). The stub generator has an error generating the stub, so I tried writing the annotation itself in Java. While this compiled correctly, when compiling tests using that annotation I get a BUG! in the Groovy compiler:
> {code}
> BUG! exception in phase 'semantic analysis' in source unit '/home/christopher/git/.../IgnoreMetaClassAttributeConverterProviderTest.groovy' com.example.DynamoDbRecord.value()
> ...
> Caused by: java.lang.NoSuchMethodException: com.example.DynamoDbRecord.value()
>     at java.lang.Class.getMethod (Class.java:2108)
>     at org.codehaus.groovy.transform.AnnotationCollectorTransform.getTargetListFromClass (AnnotationCollectorTransform.java:276)
>     at org.codehaus.groovy.transform.AnnotationCollectorTransform.getMeta (AnnotationCollectorTransform.java:76)
>     at org.codehaus.groovy.transform.AnnotationCollectorTransform.getStoredTargetList (AnnotationCollectorTransform.java:226)
>     at org.codehaus.groovy.transform.AnnotationCollectorTransform.getTargetAnnotationList (AnnotationCollectorTransform.java:356)
>     at org.codehaus.groovy.transform.AnnotationCollectorTransform.visit (AnnotationCollectorTransform.java:383)
>     at org.codehaus.groovy.transform.ASTTransformationCollectorCodeVisitor.findCollectedAnnotations (ASTTransformationCollectorCodeVisitor.java:207)
>     at org.codehaus.groovy.transform.ASTTransformationCollectorCodeVisitor.visitAnnotations (ASTTransformationCollectorCodeVisitor.java:93)
> {code}
> Adding a {{String value default ""}} to the annotation produces an NPE.
> It would make sense to me to learn that using {{AnnotationCollector}} in Java is unsupported, but the Groovy compiler should probably have a better error report.
