> I have a trait that implements another trait, and when i try to statically
> compile it with groovy 3.0.12, it throws the following error:
> {code}
> org.codehaus.groovy.control.MultipleCompilationErrorsException: startup
> failed:
> B.groovy: 12: [Static type checking] - Cannot find matching method
> <UnionType:test.T+test.B>#methodA(). Please check if the declared type is
> correct and if the method exists.
> @ line 12, column 3.
> methodA()
> ^
> 1 error
> {code}
> test case files attached. compilation:
> {code}
> JAVA_HOME=/groovy-test/jdk8u275-b01 /groovy-test/groovy-3.0.12/bin/groovyc
> -classpath /groovy-test/src B.groovy
> {code}
> all works good with 2.5.14
> when I add A into SelfType in B (so that it looks like @SelfType([T,A]), all
> compiles ok with 3.0.12 too.
> question: can adding A into SelfType be considered a safe workaround,
> provided that no class implementing B ever directly implements A?
