[jira] [Updated] (GROOVY-8127) Access to Trait$Trait$Helper#$self is forbidden

["François Guillot (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/GROOVY-8127?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

François Guillot updated GROOVY-8127:
-------------------------------------
    Description: 
I'm switching from Groovy 2.4.7 to 2.4.10 in my project.

I have a compile error with 2.4.10.
Simplified example:
{code}
import groovy.transform.CompileStatic
import org.junit.Rule
import org.junit.rules.TestRule
@CompileStatic
trait FooTrait {
    @Rule
    public final TestRule foo = {} as TestRule
}
{code}
I get "Error:Groovyc: Access to FooTrait$Trait$Helper#$self is forbidden"

Another variant of this error is "Error:Groovyc: Apparent variable '$self'
was found in a static scope but doesn't refer to a local variable, static
field or class."

This second error happens with the following code
{code}
import groovy.transform.CompileStatic
import org.junit.Rule
import org.junit.rules.TestRule
import org.junit.runner.Description
import org.junit.runners.model.Statement

@CompileStatic
trait RatpackTestSupport {

    boolean failOnResourceLeak = true

    @Rule
    public final TestRule leakDetectionFlagRule = { Statement base, Description description ->
        return {
            base.evaluate()
            if (failOnResourceLeak) {
                throw new Exception("A resource has leaked in this test!")
            }
        } as Statement
    } as TestRule

}
{code}
