[jira] [Commented] (GROOVY-9173) IllegalAccessError for class extending Java class that provides protected getProperty/setProperty

["Eric Milles (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GROOVY-9173?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16862303#comment-16862303 ] 

Eric Milles commented on GROOVY-9173:
-------------------------------------

Also, in a joint compilation situation where the Groovyc Ant task was used, we got errors for the Java stub created for the Groovy class because getProperty and setProperty are final in the base class.  The stub generation must have added public implementations of the GroovyObject methods.

>                 URL: https://issues.apache.org/jira/browse/GROOVY-9173
>             Project: Groovy
>          Issue Type: Bug
>    Affects Versions: 2.5.7
>            Reporter: Eric Milles
>            Priority: Major
>         Attachments: property-methods.zip

> Consider the following:
> PropertyBased.java
> {code:java}
> public class PropertyBased {
>   protected final Object getProperty(String name) {
>     return null;
>   }
>   protected final void setProperty(String name, Object value) {
>   }
> }
> {code}
> Whatever.groovy
> {code:groovy}
> @groovy.transform.CompileStatic
> class Whatever extends PropertyBased {
>   def getSomething() {
>     'some thing'
>   }
> }
> {code}
> No compiler errors are produced for Whatever having protected "implementations" of GroovyObject methods.  In this case, our legacy Java base class has {{getProperty}} for non-Groovy reasons.  However, when accessing {{Whatever}} from dynamic groovy code, {{IllegalAccessError}} is thrown.  See the attached (run {{gradlew test}})
