---------------------------------------

Fix Version/s: 2.4.6
TargetTypeTestGroovy passes on 2.4.6, therefore I'm closing this issue. Thanks
for reporting!
> STC error If we use java.lang.Integer as Target Type with method generics

> Key: GROOVY-7170
> URL: https://issues.apache.org/jira/browse/GROOVY-7170
> Project: Groovy
> Issue Type: Bug
> Components: Static Type Checker
> Affects Versions: 2.4.0-beta-3
> Environment: Groovy Version: 2.4.0-beta-3 JVM: 1.8.0_25 Vendor:
> Oracle Corporation OS: Mac OS X
> Reporter: UEHARA Junji
> Assignee: Pascal Schumacher
> Fix For: 2.4.6
>
> Attachments: TargetTypeTestGroovy.groovy, TargetTypeTestJava.java
>
>
> Target type inference makes an STC Error when the target is java.lang.Integer:
> {code}
> static <T> T empty() {..}
> Integer i = empty(); //[Static type checking] - Cannot assign value of
> type T to variable of type java.lang.Integer
> {code}
> Even if we specify the type explicitly, STC says same error:
> {code}
> Integer i2 = TargetTypeTestGroovy.<Integer>empty(); // [Static type
> checking] - Cannot assign value of type T to variable of type
> java.lang.Integer
> {code}
> If we use java.lang.String instead of java.lang.Integer, it's OK.
> Both of cases are worked well in java.
