[jira] [Updated] (GROOVY-9851) Private field and method use from
subclass is inconsistent
[ https://issues.apache.org/jira/browse/GROOVY-9851?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Eric Milles updated GROOVY-9851:
--------------------------------
Description:
This is probably just a slice of GROOVY-1591, GROOVY-3010, GROOVY-3142, GROOVY-5438, et al.
Adding {{super.}} qualifier causes strange behaviors. Consider the following:
{code:java}
class Foo {
private String field = 'field'
private String method() { 'method' }
}
class Bar extends Foo {
def baz() {
field // MissingPropertyException: No such property: field for class: Bar
method() // MissingMethodException: No signature of method: Bar.method()
this.field // MissingPropertyException: No such property: field for class: Bar
this.method() // MissingMethodException: No signature of method: Bar.method()
super.@field // MissingFieldException: No such field: field for class: Bar -- fixed by GROOVY-8999
// so far, so good -- although Groovy allows access to private fields and methods from outside of Bar and Foo
super.field // MissingMethodException: No signature of method: Bar.getField() -- that's strange
super.method() // returns "method" -- Why is this okay?
(super.&method)() // MissingMethodException: No signature of method: Bar.method() is applicable for argument types: () values: []
}
}
{code}
