[jira] [Updated] (GROOVY-7639) NPE when using safe traversal operator with CompileStatic

["Ben Podoll (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/GROOVY-7639?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ben Podoll updated GROOVY-7639:
-------------------------------
    Description: 
In the code below, the "if" condition throws a NPE when it reaches the "p3" object. If I remove the @CompileStatic from the "SomeOther" class it works.
{code:java}
import groovy.transform.CompileStatic

@CompileStatic
class Person {
  String name
  OtherInfo otherInfo
}

@CompileStatic
class OtherInfo {
  int favoriteNumber
}

@CompileStatic
class SomeOther {
  SomeOther() {
    Person p1 = new Person(name: 'Ben', otherInfo: new OtherInfo(favoriteNumber: 1))
    Person p2 = new Person(name: 'Aaron', otherInfo: new OtherInfo())
    Person p3 = new Person(name: 'Fred')
    [p1,p2,p3].each { Person p ->
      println "checking: ${p.name}"
      println p?.otherInfo?.favoriteNumber
      if(p?.otherInfo?.favoriteNumber == 7){
        println "luckiest number!"
      }
    }
  }
}

new SomeOther()
{code}
