I am working on an application where I am connecting to SQS queue through Apache Camel which requires only AmazonSQS client (I couldn't find any references of Camel + AWS SDK and Java 2.x) as parameter as part of SQS queue URL.
As part of the same application I am doing different operations in SQS one among them is delete message. While deleting the message from AWS SQS queue using AmazonSQS.delete(queueURL, receiptHanlde). Below is the exception being thrown by the same. However the message is being deleted from the queue. Looks like it's trying to parse the response after deleting the message and failing.
Please suggest how to resolve the exception.
