Bram, you cannot use the BlobStoreContext or BlobStore view after
closing it. Closing destroys the ExecutorService that clearContainer
uses to issue asynchronous operations. The filesystem provider does not
use asynchronous operations and thus does not have this issue. In the
future jclouds will remove its ExecutorService and require that callers
provide an external one for asynchronous calls like clearContainer.
