Paul King commented on GROOVY-7757:
-----------------------------------
Looks a little strange. The following works on master:
{code}
class Foo {
boolean allHaveCapitals = ["bAr", "baZ"].every{ word -> word.any{
it.toCharacter().isUpperCase() } }
}
assert new Foo().allHaveCapitals
assert Foo$_closure1.simpleName == '_closure1'
assert Foo$_closure1$_closure2.simpleName == '_closure2'
{code}
> Malformed class names for closures in inner classes
> ---------------------------------------------------
>
> Key: GROOVY-7757
> URL: https://issues.apache.org/jira/browse/GROOVY-7757
> Project: Groovy
> Issue Type: Sub-task
> Components: class generator
> Affects Versions: 2.4.5
> Reporter: Sam Corbett
>
> The class names generated for closures in inner classes break
> Class.getSimpleName()
> For example, the closure passed to .each in this example has name
> Example$_Inner_closure1.class:
> {code}
> public class Example {
> private class Inner {
> def _ = [1, 2, 3].each {}
> }
> }
> {code}
> Calling getSimpleName() on this class (e.g. as done by
> [Weld|http://seamframework.org/Weld] on startup) throws a
> java.lang.InternalError:
> {code}
> Caused by: java.lang.InternalError: Malformed class name
> at java.lang.Class.getSimpleName(Class.java:1133) [:1.6.0_29]
> at java.lang.Class.isAnonymousClass(Class.java:1188) [:1.6.0_29]
> {code}
> I believe the class name is expected to be in the format
> Example$Inner$closure1.
> I've attached a test case to demonstrate the problem - extract the archive,
> cd to groovy-closure-classname-test and run mvn test. The test uses Weld to
> inject a ClosureClassNameTest instance, but fails when Weld calls
> getSimpleName() on the class for the closure on line 10.
