[jira] [Created] (GROOVY-9293) CLONE - Compilation error when
accessing a protected(via `thisObject`, `owner` and
`delegate`)/package-private super class field from inside a closure
Daniel Sun created GROOVY-9293:
----------------------------------
Summary: CLONE - Compilation error when accessing a protected(via `thisObject`, `owner` and `delegate`)/package-private super class field from inside a closure
Key: GROOVY-9293
URL: https://issues.apache.org/jira/browse/GROOVY-9293
Project: Groovy
Issue Type: Bug
Components: Static compilation
Affects Versions: 2.5.8, 3.0.0-rc-1
Reporter: Daniel Sun
Assignee: Daniel Sun
Fix For: 3.0.0-rc-2
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}
