Eric Milles updated GROOVY-9653:
--------------------------------
Fix Version/s: 2.5.15
> SC: ClassCastException on delegate object property set
> ------------------------------------------------------
>
> Key: GROOVY-9653
> URL: https://issues.apache.org/jira/browse/GROOVY-9653
> Project: Groovy
> Issue Type: Bug
> Components: Static compilation
> Affects Versions: 3.0.5, 2.5.13
> Reporter: Eric Milles
> Assignee: Eric Milles
> Priority: Major
> Fix For: 4.0.0-alpha-1, 3.0.6, 2.5.15
>
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> This started to fail in Groovy 2.5.13:
> {code:groovy}
> import com.fasterxml.jackson.annotation.JsonInclude
> @Grab('com.fasterxml.jackson.core:jackson-databind:2.9.9')
> import com.fasterxml.jackson.databind.ObjectMapper
> @Grab('org.springframework:spring-web:4.3.14.RELEASE')
> import org.springframework.http.converter.json.Jackson2ObjectMapperFactoryBean
> @groovy.transform.CompileStatic
> final class MyObjectMapper extends ObjectMapper
> {
> MyObjectMapper()
> {
> super(mimicSpring())
> }
> private static ObjectMapper mimicSpring()
> {
> new Jackson2ObjectMapperFactoryBean().with {
> serializationInclusion = JsonInclude.Include.NON_NULL //
> ClassCastException:
> org.springframework.http.converter.json.Jackson2ObjectMapperFactoryBean
> cannot be cast to com.fasterxml.jackson.databind.ObjectMapper
> defaultViewInclusion = true // include w/o view tag
> failOnUnknownProperties = false
> autoDetectGettersSetters = true
> autoDetectFields = false
> afterPropertiesSet()
> return object
> }
> }
> private static final long serialVersionUID = 2643043846851474223L
> }
> println new MyObjectMapper()
> {code}
> Works fine with default (dynamic) compilation.
> In this case, the delegate (Jackson2ObjectMapperFactoryBean) and owner
> (MyObjectMapper) both supply a setter "setSerializationInclusion" and do not
> have a field of the same name.
> StaticCompilationVisitor/StaticTypeCheckingVisitor existsProperty fail to
> record the receiver type when visiting the setter.
