Subject [jira] [Updated] (GROOVY-8645) ClassCastException after checking of instanceOf
Date Thu, 14 Jun 2018 12:11:00 GMT

     [ https://issues.apache.org/jira/browse/GROOVY-8645?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Aram Arabyan updated GROOVY-8645:
---------------------------------
    Description: 
 Have grails (version 3.2.11) application (it includes groovy-2.4.11.jar). And following
code

{code}
 @CompileStatic
    def removeAllErrors(DomainClass domainInstance) {
        newAssociationOperationRunnerBuilder(domainInstance)
        .setSkipChain({DomainObjectDetails<DomainObjectDataSingle> domainObjectDetails
->
            skipValidation(domainObjectDetails.currentDomain.domainObject, domainObjectDetails.associationProp?.name)})
        .build().run({DomainObjectDetails<DomainObjectDataSingle> domainObjectDetails
->
            DomainClass domain = domainObjectDetails.currentDomain.domainObject
            if (domain instanceof GormValidateable) {
                ((GormValidateable)domain).clearErrors()
            }
            if(domain instanceof WarningsHolder) {
                WarningsHolder warningsHolder = domain as WarningsHolder //<--line 120
                Warnings warnings = warningsHolder.getWarnings()
                warnings.clearWarnings(false, true)
            }
        })
    }
{code}

And I am getting following exception

{code}
java.lang.IllegalArgumentException: java.lang.ClassCastException@58798bfb

	at groovy.lang.MetaMethod.doMethodInvoke(MetaMethod.java:325){code}

Any idea what can be the reason ? Pay attention that I have @CompileStatic there also.

========================================================================= Previous version
of this code was without @CompileStatic

{code}
 def removeAllErrors(def domainInstance) {
        newAssociationOperationRunnerBuilder(domainInstance)
        .setSkipChain({DomainObjectDetails<DomainObjectDataSingle> domainObjectDetails
->
            skipValidation(domainObjectDetails.currentDomain.domainObject, domainObjectDetails.associationProp?.name)})
        .build().run({DomainObjectDetails<DomainObjectDataSingle> domainObjectDetails
->
            domainObjectDetails.currentDomain.domainObject.clearErrors()
            if(domainObjectDetails.currentDomain.domainObject instanceof WarningsHolder) {
                Warnings warnings = domainObjectDetails.currentDomain.domainObject.getWarnings()
                warnings.clearWarnings(false, true)
            }
        })
    }
{code}

And I was getting this exception

{code}

  was:
