Paul King closed GROOVY-9873.
-----------------------------
> SAM type or functional interface referenced from a method is not visible from
> class loader
> ------------------------------------------------------------------------------------------
>
> Key: GROOVY-9873
> URL: https://issues.apache.org/jira/browse/GROOVY-9873
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 2.4.21, 2.5.14, 3.0.7, 4.0.0, 5.0.0-alpha-9
> Reporter: Eric Milles
> Assignee: Eric Milles
> Priority: Major
> Labels: indy
> Fix For: 3.0.23, 4.0.23, 5.0.0-alpha-10

> When type checked but not statically compiled, this case of method closure or
> whatever is failing for Groovy 4 but works for Groovy 3 and earlier. The
> line {{set.map(x -> x.first().intValue())}} is the source. GROOVY-9803 was
> the original issue; when broken up into separate source units, the class
> loader issue appears.
> New test case for {{groovy.transform.stc.GenericsSTCTest}}:
> {code:groovy}
> // GROOVY-9803, GROOVY-9873
> void testShouldUseMethodGenericType9() {
