Sergio del Amo created GROOVY-8912:
--------------------------------------

             Summary:  Cannot cast object  ... with class 'java.lang.Class' to 
class 'groovy.lang.GroovyObject'
                 Key: GROOVY-8912
                 URL: https://issues.apache.org/jira/browse/GROOVY-8912
             Project: Groovy
          Issue Type: Bug
    Affects Versions: 2.5.4
            Reporter: Sergio del Amo


This code

{{MetaProperty idProp = 
getJavaClass().getMetaClass().getMetaProperty(GormProperties.IDENTITY)}}

 

throws the next error:

 

{{org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast 
object 'class grails.gorm.tests.path.domain.Person' with class 
'java.lang.Class' to class 'groovy.lang.GroovyObject' at

at 
grails.gorm.tests.path.PathSpec.$spock_initializeSharedFields(PathSpec.groovy:16)}}

 

But this is ok: 

 

{{Class clazz = getJavaClass()}}
{{MetaClass metaClass = clazz.getMetaClass()}}
{{MetaProperty idProp = metaClass.getMetaProperty(GormProperties.IDENTITY)}}

 

 

{\{ GormProperties.IDENTITY is String defined in an interface in a .java file. 
}}

  

*Steps to reproduce:.*

You can find a link to the commit here:

[https://github.com/grails/gorm-neo4j/commit/70a6321b902377303b762cc2cdb9e3f2c9a4b794]

 

Cloning the repo, reverting that commit and execute: 

 

./gradlew --stacktrace grails-datastore-gorm-neo4j:test --tests 
grails.gorm.tests.path.PathSpec

 

and compilation fails
