      Description

       Have grails (version 3.2.11) application (it includes groovy-2.4.11.jar). And following 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)
                  }
              })
          }
      

      And I am getting following exception

      java.lang.IllegalArgumentException: java.lang.ClassCastException@58798bfb

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

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

       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)
                  }
              })
          }
      

      And I was getting this exception

      com.webbfontaine.sw.sad.ci.Item cannot be cast to com.webbfontaine.sw.sad.ci.Item_$$_jvst840_3. Stacktrace follows: java.lang.ClassCastException: com.webbfontaine.sw.sad.ci.Item cannot be cast to com.webbfontaine.sw.sad.ci.Item_$$_jvst840_3 at com.webbfontaine.grails.plugins.validation.rules.DocVerificationService$_removeAllErrors_closure5.doCall(DocVerificationService.groovy:111)
