> 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!"
>       }
>     }
