Description

import groovy.transform.CompileStatic

interface Row {
    int getKey()
}

class RowImpl implements Row {
    int getKey() { 1 }
}

@CompileStatic
def test() {
    def rows = [new RowImpl(), new RowImpl(), new RowImpl()]
    
    rows.each { Row row ->
        println row.key
    }
}

test()

When executing the above script, with the statically compiled test() method, I get an exception saying that the owner property could not be found:

Furthermore, if you look closely at the stacktrace, it seems strange to see some call sites appearing, as if the closure wasn't compiled statically.
