-----------------------------
> AutoClone throws ClassCastException when used with @ToString or
> @EqualsAndHashCode
> ----------------------------------------------------------------------------------
>
> Key: GROOVY-9009
> URL: https://issues.apache.org/jira/browse/GROOVY-9009
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 2.5.5
> Reporter: Amin Ziaei
> Assignee: Paul King
> Priority: Critical
> Fix For: 3.0.0-beta-1, 2.5.7
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> 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.
