Description

If you have a class that is extended by another class and there is a private setter in the class that is extended, that setter cannot be found at runtime. Example script attached. At runtime, the following exception trace is shown:

groovy.lang.MissingPropertyException: No such property: $priv for class: com.my_example.ExtendedBugClass
Possible solutions: $pub

at com.my_example.BugClass.test(StaticSetterBug.groovy:27)

at com.my_example.ExtendedBugClass.run(StaticSetterBug.groovy:37)

at com.my_example.ExtendedBugClass$run.call(Unknown Source)

at com.my_example.StaticSetterBug.run(StaticSetterBug.groovy:42)

at jdk.internal.reflect.GeneratedMethodAccessor305.invoke(Unknown Source)

at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)

 Note: Problem occurs regardless of whether classes are dynamic or static compiled. The '$' in the names has no effect, a letter in its place has same problem. The extending class does not have this problem. A stand alone class also does not have this problem. If the setter is public or protected, the problem goes away. Private getters do not display the problem.
