Jochen Theodorou commented on GROOVY-9516:
------------------------------------------
Eric, would it not be better to handle this like an if-else and eval the type
of z to A here?
> Static compiler infers wrong type for implicitly shared variables
> -----------------------------------------------------------------
>
> Key: GROOVY-9516
> URL: https://issues.apache.org/jira/browse/GROOVY-9516
> Project: Groovy
> Issue Type: Bug
> Components: Static compilation
> Affects Versions: 3.0.0, 2.5.11
> Reporter: Konstantin Nisht
> Priority: Major
>
> Consider the following code
> {code:groovy}
> class A {}
> class B extends A{ def b() {}}
> class C extends A{}
> @CompileStatic
> static foo() {
> def x = new B()
> ({ x = new C() })()
> def z = x
> z.b()
> }
> {code}
> Here type of {{z}} in the last line of the method is deduced to be {{B}}.
> Attempt to execute {{z.b()}} leads to cast exception, which is unexpected
> under static compilation.
