Hi,

I’ve run into the same thing myself. The same code works on the AWS Java SDK 1.5.8, but doesn’t ( however should ) with 1.6.12 and 1.7.12 ( the latest ). I’ve also tested using the 1.3.x SDK, and works fine.

This is all with Wowza Streaming Engine 4.0.3.01 and 4.0.3.03, and connecting to DynamoDB rather than S3, and on Sun Java 1.8.0\_05.

We noticed this when we ported custom modules to Wowza 4 (and they worked) and upgraded the AWS SDK which then caused all kind of problems.

Hope this helps.

#Edit: Referring to the post you mention above, my testing is on a local development machine rather than on the EC2 instance itself, using fixed user credentials.
