Description

Already asked the question in the mailing list. Claus Ibsen stated that this is actually a bug: 

Ad 1)
Yes that seems like a little bug. You are welcome to create a JIRA ticket.

Here is my description of the bug:
<dependency>
    <groupId>org.apache.camel.springboot</groupId>
    <artifactId>camel-azure-storage-blob-starter</artifactId>
    <version>3.7.0</version>
</dependency>

We are currently trying to integrate azure cloud by using the camel-azure-storage-blob component. Everything works fine until we activate stream caching and camel starts to spool the payload. In this case we get the following error:

Caused by: java.lang.IllegalArgumentException: InputStream of body exchange does not support mark/rest operations.

            at org.apache.camel.component.azure.storage.blob.BlobStreamAndLength.createBlobStreamAndLengthFromExchangeBody(BlobStreamAndLength.java:52)

            at org.apache.camel.component.azure.storage.blob.operations.BlobOperations.uploadBlockBlob(BlobOperations.java:181)

I have looked into the source and think that the component does not load the stream properly from the FileInputStreamCache object.
