tkobayas opened a new issue, #6696:
URL: https://github.com/apache/incubator-kie-drools/issues/6696
DRL10 currently rejects Java diamond operators in function bodies due to a
parser grammar gap;
```java
function List<String> testOfGenerics(String a) {
List<String> results = new ArrayList<>();
return results;
}
```
```

```
explicit type arguments are a valid workaround until the fix is released.
```java
function List<String> testOfGenerics(String a) {
List<String> results = new ArrayList<String>();
return results;
}
```
