>                 Key: GROOVY-10909
>                 URL: https://issues.apache.org/jira/browse/GROOVY-10909
>             Project: Groovy
>          Issue Type: Improvement
>          Components: bytecode, Compiler, Static compilation
>            Reporter: Eric Milles
>            Assignee: Eric Milles
>            Priority: Minor
>              Labels: bytecode
>             Fix For: 5.0.0-alpha-1

> Consider the following:
> {code:groovy}
> List getList() { ['xx'] }
> @groovy.transform.CompileStatic
> void test(object) {
>   def others = [], strings = []
>   if (object in list) { // 4 of 8 branches missed
>     strings << object
>   }
>   if (!(object in list)) { // 4 of 10 branched missed
>     others << object
>   }
>   println others
>   println strings
> }
> test(null)
> test('xx')
> test([''])
> {code}
> When unit testing, I noticed 4 of 10 branches missed for "if (!(item in list)) ...".  When compiled and executed dynamically, it shows 2 of 2 branches covered (safe call to "list.isCase(item)").
> Static compilation transforms "item in list" into "list == null ? item == null : list.isCase(item)".  This is certainly where all the branches are coming from.
