[jira] [Resolved] (GROOVY-9009) AutoClone throws ClassCastException when used with @ToString or @EqualsAndHashCode

     [ https://issues.apache.org/jira/browse/GROOVY-9009?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Paul King resolved GROOVY-9009.
-------------------------------
       Resolution: Fixed
         Assignee: Paul King
    Fix Version/s: 2.5.7
                   3.0.0-alpha-5

Should be fixed in the next release. A possible workaround would be to remove @CompileStatic from the class and just place it on any methods.

> Let’s say I have the following class:
> {code:java}
> @ToString(includes = 'someId')
> @CompileStatic
> @AutoClone
> class SomeClass {
>   String someId
> }
> {code}
> When I call clone, I get the following exception:
> {code:java}
> org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'com.some.package.SomeClass(null)' with class 'com.some.package.SomeClass' to class 'java.lang.StringBuilder'
> {code}
> When I look at the decompiled .class file in Intellij, I see the following clone method has been generated:
> {code:java}
> @Generated
> public SomeClass clone() throws CloneNotSupportedException {
>   StringBuilder _result = (StringBuilder)ScriptBytecodeAdapter.castToType((SomeClass)ScriptBytecodeAdapter.castToType(super.clone(), SomeClass.class), StringBuilder.class);
>   return (SomeClass)ScriptBytecodeAdapter.castToType(_result, SomeClass.class);
> }
> {code}
> The issue is not reproducible if I remove the @ToString on the class.
