    -------------------------------------

was (Author: JIRAUSER304394):
I suspect gcsObject can never be null because [https://cloud.google.com/storage/docs/json_api/v1/objects/get]
{noformat}
By default, this responds with an object resource in the response body. If you provide the URL parameter alt=media, then it will respond with the object data in the response body.{noformat}

>             Project: jclouds
>          Issue Type: Bug
>          Components: jclouds-blobstore
>    Affects Versions: 2.7.0
>            Reporter: Aliaksandr
>            Priority: Major
>              Labels: google-cloud-storage

> *Steps to reproduce*
> * Configure blob store using `google-cloud-storage`
> * Try to get a blob which doesn't exist
> * The error occurred something like below
> {noformat}
> java.lang.NullPointerException: Cannot invoke "java.lang.Long.longValue()" because the return value of "org.jclouds.io.MutableContentMetadata.getContentLength()" is null
> 	at org.jclouds.googlecloudstorage.blobstore.GoogleCloudStorageBlobStore.getBlob(GoogleCloudStorageBlobStore.java:254)
> 	at org.jclouds.blobstore.internal.BaseBlobStore.getBlob(BaseBlobStore.java:217)

> 	at jdk.proxy3.$Proxy129.getBlob(unknown)
> {noformat}
> *Root cause*
> The attribute `Content-Length` might be null in `org.jclouds.io.ContentMetadata#getContentLength` but the code does a cast to primitive type(see `org.jclouds.googlecloudstorage.blobstore.GoogleCloudStorageBlobStore#getBlob`):
> {noformat}
> Payload payload = api.getObjectApi().download(container, Strings2.urlEncode(name), httpOptions).getPayload();
> long contentLength = payload.getContentMetadata().getContentLength();
> {noformat}
