-----------------------------------------------

             Summary: NPE when processing the AST of nested annotations from JAR files
                 Key: GROOVY-9871
                 URL: https://issues.apache.org/jira/browse/GROOVY-9871
             Project: Groovy
          Issue Type: Bug
            Reporter: Alvaro Sanchez-Mariscal


Source: [https://github.com/micronaut-projects/micronaut-openapi/issues/313]

This source:

 
{code:java}
@JsonSubTypes([
        @JsonSubTypes.Type(value = Dog, name = "dog"),
        @JsonSubTypes.Type(value = Cat, name = "cat")
])
Animal animal
{code}
Will cause [GroovyCodeVisitor|https://github.com/apache/groovy/blob/GROOVY_3_0_4/src/main/java/org/codehaus/groovy/ast/GroovyCodeVisitor.java#L202] to throw a NPE because the {{list}} parameter is {{null}}.
