-----------------------------------
Summary: GCP BlobStore fails to get blob
Key: JCLOUDS-1646
URL: https://issues.apache.org/jira/browse/JCLOUDS-1646
Project: jclouds
Issue Type: Bug
Components: jclouds-blobstore
Affects Versions: 2.7.0
Reporter: Aliaksandr
*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

*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}
