Description

It looks like constructor annotation information is not populated in the AST for classes loaded from the classpath in this block of code in org.codehaus.groovy.vmplugin.v5.Java5#configureClassNode: https://github.com/apache/groovy/blob/master/src/main/java/org/codehaus/groovy/vmplugin/v5/Java5.java#L388. What seems to be missing are calls to setAnnotationMetaData() like in the block above for methods.

I found this bug accidentally when using @InheritConstructors(constructorAnnotations = true)) and not seeing the annotations copied onto inherited constructors in some cases which turned out to be when the superclass of the class annotated with @InheritConstructors is not part of the compiled sources but is loaded from a jar.
