Doc Text:
In previous versions of the product, the threads used for mounting deployment content were not marked as daemon threads. As a result, when an appclient container was shut down, the process would not terminate because the deployment mounting thread would not terminate. In this release, the threads used for mounting deployment content are marked as daemon threads and the appclient container will shut down properly.

I'm not sure if it is the same problem, but I see hanging server process on windows. I'm attaching stack, I can provide heap dump as well.
