-----------------------------------
Assignee: Eric Milles
> Type argument inference does not work in closure
> ------------------------------------------------
>
> Key: GROOVY-9970
> URL: https://issues.apache.org/jira/browse/GROOVY-9970
> Project: Groovy
> Issue Type: Bug
> Components: Static compilation, Static Type Checker
> Reporter: Stefanos Chaliasos
> Assignee: Eric Milles
> Priority: Major
>
> I have the following Groovy program.
> {code:groovy}
> class Foo {}
> final class A<T extends Foo> {
> public T x;
> A(T x) {
> this.x = x;
> }
> }
> @groovy.transform.CompileStatic
> public class C<T extends Number> {
> public void foo(T args) {
> final A<Foo> x = new A<>(new Foo()); // compiles
> def closure = p -> {
> final A<Foo> y = new A<>(new Foo()); // does not compile
> }
> }
> }
> {code}
> h2. Actual Behavior
> The program does not compile, and I get the following error.
> {code:java}
> org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
> Foo.groovy: 15: [Static type checking] - Cannot call A#<init>(T) with arguments [Foo]
> @ line 15, column 26.
> final A<Foo> y = new A<>(new Foo());
> ^
> 1 error
> {code}
> h2. Expected Behavior
> Compile successfully.
> h2. Comment
> This should be a regression bug because it compiles with the 3.0.7 compiler and the 4.0.0-alpha-2.
> h2. Affected Version
> This programs fails when compiled with the compiler from the master (commit: 5d2944523f198d96b6515e85a24d2b4e43ce665f).
