The error you're seeing in your Tomcat server logs is related to the AWS Blu Age runtime environment. The specific error "Unexpected attention key: 'CLOSE'" indicates an issue with the JICS (Java Implementation of CICS) component of the Blu Age runtime when processing an attention key.

This type of error typically occurs when the application is trying to handle a terminal attention key that it doesn't recognize or isn't properly configured to handle. In this case, the "CLOSE" key is causing the issue.

Here are some potential solutions:

1. Check your application configuration files, particularly those related to terminal emulation or screen handling in the Blu Age environment.

2. You might need to add a configuration parameter to your application-main.yml file to make the application more tolerant of unrecognized program calls or attention keys. Try adding:
`stopExecutionWhenProgNotFound: false`

3. Review any recent changes to your application's screen handling or terminal emulation components that might have introduced this issue.

4. If you're working with the CardDemo application in a workshop environment, verify that all components are properly configured according to the workshop instructions.

5. Check for any whitespace issues in your IDCAMS commands if you're working with VSAM datasets, as improper spacing can cause unexpected behavior in Blu Age applications.

If the issue persists, you may need to examine the specific transaction or screen that's generating this error and review its implementation details.
