It wasn't intentional then, was it?

I guess it does, `othervm` tests launch a new VM for each test as opposed to re-using an already running VM.

Anyway, removing `/othervm` isn't strictly required because `java/beans` are run in `othervm` mode.

https://github.com/openjdk/jdk/blob/d1540e2a49c7a41eb771fc9896c367187d070dec/test/jdk/TEST.ROOT#L48-L49

It caught my attention because `/othervm` is removed from tests in `beans/XMLEncoder/*/`, that is in subfolders, whereas in the `beans/XMLEncoder/` folder these are left.
