How access native provider API with Jclouds 1.7

Question

Using JClouds, up to version 1.6.x it was possible to access to the native EC2 provider API by using the following idiom:

AWSEC2Client ec2Client = AWSEC2Client.class.cast(context.getProviderSpecificContext().getApi());

Actually, I copied from the documentation page: http://jclouds.apache.org/guides/aws/

It turns out that in the latest release this method has been removed. Is there an alternative method/way to access to the provider specific features (security groups, key-pairs, etc)?

Unwrapping the API from the ComputeServiceContext

ComputeServiceContext context = ContextBuilder.newBuilder("aws-ec2")
    .credentials("accessKey", "secretAccessKey")
    .buildView(ComputeServiceContext.class);
ComputeService computeService = context.getComputeService();
AWSEC2Api ec2Api = context.unwrapApi(AWSEC2Api.class);

Building the API directly

AWSEC2Api ec2Api = ContextBuilder.newBuilder("aws-ec2")
    .credentials("accessKey", "secretAccessKey")
    .buildApi(AWSEC2Api.class);
