Christopher Smith commented on GROOVY-10570:
--------------------------------------------
I suspected it was something in this genre. In this case, my request would
be for a defensive check in the Groovy compilation that outputs an
affirmative "You didn't compile this with Groovy last time" rather than an
NPE or similar.

> Key: GROOVY-10570
> URL: https://issues.apache.org/jira/browse/GROOVY-10570
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 4.0.1
> Reporter: Christopher Smith
> Priority: Minor
>
> 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)

> {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.
