[jira] [Comment Edited] (GROOVY-9987) MissingMethodException when a base class calls a static method inside a closure

We have a few open issues for accessing private members from a closure when "this" is a subclass instance.  {{@CompileStatic}} can be used (on {{baseRun()}}) to employ bridge methods that allow this to work as expected.

> If a class calls a method on a base class and that method class a static method inside a closure a MissingMethodException will be thrown at runtime.
> Try executing the attached script with Groovy 3.0.7. It will yield:

> Caught: groovy.lang.MissingMethodException: No signature of method: StaticTest.baseRunStatic() is applicable for argument types: () values: []
