Eric Milles resolved GROOVY-9919.
---------------------------------
Resolution: Information Provided
> getProperty('Foo') fails, when a function setFoo(foo [, ....]) exists (Foo
> starting with uppercase letter)
> ----------------------------------------------------------------------------------------------------------

> Key: GROOVY-9919
> URL: https://issues.apache.org/jira/browse/GROOVY-9919
> Project: Groovy
> Issue Type: Bug
> Components: groovy-runtime
> Affects Versions: 3.0.5
> Environment: Groovy >= 3..0.5
> Java JDK jdk1.8.0_141
> Windows 7 Prof 64 bit
> Reporter: Stefan Großkreutz
> Priority: Major
>
> Hello,
> we upgrade lately from Groovy 2.4 to Groovy 3.0.4 and then to 3.0.6. From
> this point some of our scripts started to fail. I reduced the source to the
> very problem, see example below.
> Consider a class {{MyClass}} having a property {{Foo}} (mind the upper case
> name!).
> The class has a function {{setFoo( String foo, String bar = '')}} which acts
> in our case as a convenience function to set two or more other properties in
> the class.
> When we try to access the Property with {{getProperty("Foo"),}} we now get an
> Exception:
> {{groovy.lang.MissingPropertyException: No such property: Foo for class:
> MyClass}}
> {{Possible solutions: foo}}
> From the outside it looks as if the function creates an new lowercase
> property {{foo}} behind the scenes and hides or destroys the uppercase
> property.
> Last Groovy version where the example runs correctly ist 3.0.4, so Groovy
> 3.0.5 introduced the problem.
> {code:java}
> public class MyClass {
>
> public String Foo
> public String Bar
> // both these variants cause the error
> void setFoo(String foo, String bar = '' )
> // void setFoo(String foo )
>
> // these variants are working
> // void setFoo(String foo, String bar )
> // void setStateWithInfo(String foo, String bar = '' )
> {
> Foo = foo
> Bar = bar
> }
> }
> MyClass myClass = new MyClass()
> myClass.Foo = '42'
> // no need to call the function actually
> // myClass.setFoo('42', 'foo info')
> assert myClass.Foo == '42'
> Object foo = myClass.getProperty('Foo') // <-- crashes in Groovy 3.0.5 up
> println "foo is $foo"
> assert foo == '42'
> {code}
