Andrew Gaul commented on JCLOUDS-1646:
--------------------------------------
Which kinds of blobs have this behavior? The code checks {{gcsObject == null}}
above so I don't understand the cause.
This appears to be a regression from 2.6.0 since I added this in
6b5185536586cd89c9645c37052d60c4f6c60a73. Can you downgrade to 2.6.0 as a
workaround?
> 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
> 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.internal.reflect.NativeMethodAccessorImpl.invoke0(native)

> jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:77)

> at java.lang.reflect.Method.invoke(Method.java:568)
> at
> com.google.inject.internal.DelegatingInvocationHandler.invoke(DelegatingInvocationHandler.java:50)
> 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}
