Daniel Sun commented on GROOVY-7165:
------------------------------------
We should forbidden accessing `private` members from other classes.
{code:java}
class Base {
private static final String CONST = 'const'
}
class C extends Base {
static main(args) {
println Base.CONST // I expect some error here
println CONST // throws MissingPropertyException
}
}
{code}
> Static Compilation: private static field accessed from a Closure produces a
> runtime error
> -----------------------------------------------------------------------------------------
>
> Key: GROOVY-7165
> URL: https://issues.apache.org/jira/browse/GROOVY-7165
> Project: Groovy
> Issue Type: Bug
> Components: Static compilation
> Affects Versions: 2.3.7
> Reporter: Neil Galarneau
> Priority: Major
>
> The following code compiles cleanly but throws an exception at runtime.
> This code doesn't have a stack trace. The code I simplified this from, did
> have a stack trace.
> If I remove 'private' from staticfield, then it works:
> {code}
> @CompileStatic
> class TestPrivateStaticFieldInClosure extends BaseBug
> {
> public static void main(String[] args)
> {
> (new TestPrivateStaticFieldInClosure()).show()
> }
> }
> @CompileStatic
> class BaseBug
> {
> private static ArrayList<String> staticfield = new ArrayList<>()
> void show()
> {
> List<Function<List<String>, String>> runners = new ArrayList<>()
> runners.add(new Called())
> List<String> cmds = ["hello"]
> runners.each { cmds.addAll(it.apply(staticfield)) }
> println cmds.size()
> }
> class Called implements Function<List<String>, String>
> {
> @Override
> String apply(List<String> strings) {
> "groovin"
> }
> }
> }
> {code}
