Eric Milles commented on GROOVY-8978: ------------------------------------- See proposed solution in GROOVY-9007 > NPE when accessing protected method from subclass clone > ------------------------------------------------------- > > Key: GROOVY-8978 > URL: https://issues.apache.org/jira/browse/GROOVY-8978 > Project: Groovy > Issue Type: Bug > Affects Versions: 2.5.6 > Reporter: paolo di tommaso > Priority: Major > > I'm getting a NPE when running this snippet: > {code} > @groovy.transform.CompileStatic > class LazyMap implements Map<String,Object> { > @Delegate protected Map<String,Object> target > LazyMap() { > target = new HashMap<>() > } > } > @groovy.transform.CompileStatic > class TaskConfig extends LazyMap implements Cloneable { > TaskConfig() { } > TaskConfig clone() { > def copy = (TaskConfig)super.clone() > copy.target = new HashMap<>(this.target) > return copy > } > } > {code} > The problem is that `this.target` in the clone method is evaluated to `null`. > It works fine if the classes are not declared CompileStatic. It was also > working fine with groovy version prior to 2.5.6. > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
