Eric Milles reopened GROOVY-7996:
---------------------------------
Assignee: (was: Paul King)
Rolling back initial changes for this issue. There were a number of other
issues created by this and I think the case of a delegate having the same
property name as an owner field is a bit less likely of a use case than the
others.
A number of test cases have been added so if a fix is approached for this
again, there will be less chance of breaking other closure variable expression
access scenarios.
> Using with method with a closure that references a protected property
> produces ClassCastException

> Key: GROOVY-7996
> URL: https://issues.apache.org/jira/browse/GROOVY-7996
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 2.4.7
> Reporter: Graeme Rocher
> Priority: Major
> Fix For: 2.5.6, 3.0.0-beta-1
>
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> The following example:
> {code}
> class Foo {
> Object propertyMissing(String name) {
> return "stuff"
> }
>
> void build(Closure callable) {
> this.with(callable)
> }
> }
> @groovy.transform.CompileStatic
> class Bar {
> protected List bar = []
>
> boolean doStuff() {
> Foo foo = new Foo()
> foo.build {
> return bar.isEmpty()
> }
> }
> }
> new Bar().doStuff()
> {code}
> Produces
> {code}
> java.lang.ClassCastException: java.lang.String cannot be cast to
> java.util.List
> at Bar$_doStuff_closure1.doCall(ConsoleScript3:19)
> at Bar$_doStuff_closure1.call(ConsoleScript3)
> at
> org.codehaus.groovy.runtime.DefaultGroovyMethods.with(DefaultGroovyMethods.java:242)
> at Bar.doStuff(ConsoleScript3:18)
> at Ba
> {code}
> The equivalent code without CompileStatic prints:
> {code}
> Result: false
> {code}
> The behaviour of both should be he same IMO
