recursive type references in your code

The error message you're encountering indicates a problem related to recursive type references in your code. This typically occurs when there's a circular dependency or incorrect type resolution during caching of types, especially in environments using libraries like Guava for concurrency and caching.

Here are steps you can take to address this issue:

1. Check for Circular Dependencies: Review the class XXX and any classes it references. Ensure there are no circular dependencies where Class A depends on Class B, and Class B depends on Class A directly or indirectly.

2. Review Caching Mechanisms: If you're using caching mechanisms like Guava's CacheBuilder, ensure that cached types and their dependencies are properly resolved and do not create circular references that lead to recursive type resolution errors.

3. Update Library Versions: Sometimes, such issues are fixed in newer versions of libraries like Guava. Ensure you are using the latest stable version of Guava or the library you suspect is causing the issue.

4. Modify Class Dependencies: If possible, refactor your code to eliminate circular dependencies. This might involve restructuring how classes interact or breaking dependencies into interfaces and implementations where appropriate.

5. Debugging: Use debugging tools to trace the error back to its source. Look for specific instances where the recursive reference to DeviceStatisticDay might be triggered incorrectly.

6. Consult Documentation and Community: Check the documentation of Guava or the library you're using for caching to see if there are specific guidelines or known issues related to recursive type resolution.

By systematically addressing these points, you should be able to identify and resolve the recursive type resolution issue causing the UncheckedExecutionException
