> Unable to infer the type parameter of a parameterized function

>
> Key: GROOVY-10222
> URL: https://issues.apache.org/jira/browse/GROOVY-10222
> Project: Groovy
> Issue Type: Bug
> Components: Static Type Checker
> Reporter: Thodoris Sotiropoulos
> Assignee: Eric Milles
> Priority: Major
>
> I have the following program
> {code:java}
> class A {
> static <T> T foo() {
> return null;
> }
> }
> class Test<T> {
> void bar() {
> T x = A.foo();
> }
> }
> {code}
> h3. Actual Behaviour
> {code:java}
> org.codehaus.groovy.control.MultipleCompilationErrorsException: startup
> failed:
> groovy11.groovy: 9: [Static type checking] - Cannot assign value of type #T
> to variable of type T
> @ line 9, column 15.
> T x = A.foo();
> ^1 error
> {code}
> h3. Expected Behaviour
> Compile successfully
>
> I don't know however, if this is a limitation of the inference engine of
> groovyc or a bug. Note that the Java compiler compiles the above program
> successfully. Also note that if I replace "T x = A.foo()" with "String x =
> A.foo()", groovyc compiles the updated program.
