AWS Bluage - jdk version mismatch during Ant build

The error you're encountering is due to a version mismatch between the JDK specified in your Ant build configuration and the JDK available in your AppStream environment.

To resolve this issue, you need to update your Ant build configuration in Eclipse to use the available JDK version (17.0.10) instead of looking for JDK 11.0.15.1. Here's how to fix it:

1. In Eclipse, go to Window > Preferences > Ant > Runtime
2. Check the Ant Home directory to ensure it's pointing to the correct Ant installation
3. Go to the "JRE" tab in the same Ant Runtime preferences
4. Update the JRE/JDK configuration to use the available Corretto 17.0.10 JDK instead of JDK 11.0.15.1
5. Apply the changes and close the preferences dialog
6. Clean and rebuild your project

Alternatively, you can also modify your Ant build script (package.xml) to explicitly use the available JDK version instead of relying on the default configuration.

This issue is common in the AWS Blu Age L3 Workshop environment when there's a mismatch between the JDK version specified in the build configuration and the one available in the AppStream environment. It's important to ensure that all components (JDK version, Blu Age version, etc.) are aligned properly for the workshop exercises to work correctly.
