With enabled validation, data handler returns empty input stream for attachment data.
1. Unzip the attachment
2. Build using "mvn clean install" and deploy war file to JBoss EAP 7.1.2.
3. Try calling the deployed soap service with attachments as given in the sample soap UI project.
4. Notice the resulting file is empty. This happens only when schema validation enabled. After removing SchemaValidation annotation it works fine.
