Daniel Sun updated GROOVY-9292:
-------------------------------
Description:
Compilation fails when accessing a protected(via `thisObject`, `owner` and
`delegate`)/package-private super class field from inside a closure:
{code:java}
GroovyShell shell = new GroovyShell()
shell.evaluate('''
package a
import groovy.transform.CompileStatic
@CompileStatic
abstract class Abstract_Class {
protected String protectedField = 'field' // `@PackageScope` fails too
abstract String doThing()
}
assert true''')
shell.evaluate('''
package b
import a.Abstract_Class
import groovy.transform.CompileStatic
@CompileStatic
class ConcreteClass extends Abstract_Class {
@Override
String doThing() {
'something'.with {
return owner.protectedField // `thisObject.protectedField`,
`delegate.protectedField` fails too
}
}
}
assert true''')
shell.evaluate("assert new b.ConcreteClass().doThing() == 'field'")
{code}
*Note:* accessing a package-private super class field from inside a closure via
`this` still fails, we will open a new ticket to track it:
{code:java}
GroovyShell shell = new GroovyShell()
shell.evaluate('''
package a
import groovy.transform.CompileStatic
@CompileStatic
abstract class Abstract_Class {
@groovy.transform.PackageScope String superField = 'field'
abstract String doThing()
}
assert true
''')
shell.evaluate('''
package a
import a.Abstract_Class
import groovy.transform.CompileStatic
@CompileStatic
class ConcreteClass extends Abstract_Class {
@Override
String doThing() {
this.with {
return this.superField
}
}
}
assert true
''')
shell.evaluate("assert new a.ConcreteClass().doThing() == 'field'")
{code}
