To find Scala companion mudule from Java in mixed sources, we should strip module suffix `$`. This provides workaround for #17255, but it requires some refinment to fix it because not-fully-qualified type like the following example still fails to compile due to missing symbol. ```java package example; public class Bar { private static final Foo$ MOD = Foo$.MODULE; } ``` This is because `pre` in `javaFindMember` for `Foo` in the case above is `<root>`, not `example` and therefore `pre.findMember` looks for `<root>.Foo` instead of `example.Foo`. I'm not sure whether the qualifier is intentionally dropped. References - #12884 - scala/scala#7671 [Cherry-picked 22d98d6][modified]
Avoid skipping searchin a member by the original name even when name is likely companion module name. [Cherry-picked 4cb34e5]
