[Groovy] TestAnnotationValue.groovy: -1: Attribute 'shortProp2' should have type 'java.lang.Short'; but found type 'java.lang.Integer' in @test.bug.annotation.TestAnnotation

Groovy

Bug Report

1. Error - 오류

이전에는 Annotation Interface를 정의 할 때 문제가 발생했었는데 (https://issues.apache.org/jira/browse/GROOVY-6025)

이번 Error는 Annotation을 적용하고 short값을 정의 할 때 문제가 발생한다.

Test해 본 결과, 2.5.4 버전부터 발생하는 것으로 보인다. ㅠ_ㅠ

\\some\\project\\TestAnnotationValue_Groovy.groovy: -1: Attribute 'shortProp2' should have type 'java.lang.Short'; but found type 'java.lang.Integer' in @test.bug.annotation.TestAnnotation

• 동작하는 버전

  • Groovy between 2.1.3 and 2.5.3 (tested by 2.1.3 / 2.4.13 / 2.5.3)

• 동작하지 않는 버전

  • Since Groovy 2.5.4. (tested by 2.5.4 / 2.5.14 / 3.0.8)

2. Problem - 문제

버그 같다. 또는 지원하지 않을 것 같다.

3. Not Solved - 미해결

short을 사용하지 않고 int로 우회해서 사용해야 할 것 같다.

개인적으로 이건 꼭 개선되었으면 해서 Groovy Jira에 찾아가서 report를 남겼다.

• Cannot compile when set short value to annotation by already defined short variable since version 2.5.4: https://issues.apache.org/jira/browse/GROOVY-10068
