JBoss ON CLI requires maximum heap setting many times higher then the size of a file being uploaded using the CLI

Issue

• Huge amount of memory required for WAR upload using CLI
• The Command-Line Interface (CLI) ran out of memory during upload operation
• Deployment of 60 MB WAR file requires JVM memory of 512 MB.
• Why does the amount of memory seem huge if compared with the deployment file size?
• Is there any way to reduce the memory consumption when deploying via the CLI?
• CLI requires many times more JVM heap then the file size being deployed.

• Deployment of a 40 MB WAR file using the CLI results in:
