Seems like a bug. I added a simpler test case and some ideas for workarounds in the bug report. The player team doesn't like working with Flex-based test cases.
I think the simplest thing to do for now (besides setting loadForCompatibility=true) is to find a way to inject common classes into the main applicationDomain before loading any child SWF that uses those classes. I listed one of my blog posts in the bug report that show how to do that.

(The Thing type is *not* known to the parent application.) The first sub-application can declare a Vector.<Thing> and add Thing objects to it, but if the second sub-app tries to do the same, a type error is thrown. Is this a known limitation of Vector/sub-applications? Are there any known workarounds? There's some code that demonstrates the problem attached to https://bugs.adobe.com/jira/browse/FP-1986.
