Anton Pryamostanov updated GROOVY-8938:
---------------------------------------
Description:
Note: **this seems to be a quite major issue**, kindly look at this one with
emphasis.
Please see the below test case:
SubClass extends the SuperClass and overrides the field "inheritedField".
{code}
class OtherClass {
String otherField
OtherClass(String otherField) {
this.otherField = otherField
}
String toString() {
return otherField
}
}
class SuperClass {
final OtherClass inheritedField = new OtherClass("Super Class String")
}
class SubClass extends SuperClass {
final OtherClass inheritedField = new OtherClass("Sub Class String")
}
SuperClass superClass = new SuperClass()
SubClass subClass = new SubClass()
assert subClass.inheritedField.toString() == "Sub Class String"
{code}
*Actual result*: assertion fails
*Expected result*: assertion should pass
*Note*: If "final" modifier is removed, assertion passes as expected.
This seems an issue with final field caching.
Assertion error text:
{code}
Assertion failed:
assert subClass.inheritedField.toString() == "Sub Class String"
| | | |
| | | false
| | 'Super Class String'
| Super Class String
