Christopher Smith created GROOVY-9821:
-----------------------------------------
Summary: STC doesn't recognize interface-based properties
Key: GROOVY-9821
URL: https://issues.apache.org/jira/browse/GROOVY-9821
Project: Groovy
Issue Type: Bug
Components: Static Type Checker
Affects Versions: 3.0.6
Reporter: Christopher Smith
I have been unable to create a more minimal MCVE, but this is reproducable at
will using the Spring Security libraries.
The following method definition:
{code:groovy}
def authorities(Authentication auth) {
auth.authorities*.authority
}
{code}
produces an error
{code}
No such property: authority for class: java.util.Collection <? extends
org.springframework.security.core.GrantedAuthority>
{code}
It should be attempting to spread the property access onto the collection's
element type, not the collection itself. Using {{*.getAuthority()}} works as
expected. I could not replicate with an inline Groovy test case; the resolution
works, but invoking against the {{Authentication}} class reliably produces the
error.
