Setting up a new spring boot application and running into an issue only in deployed env

So, I recently started a new spring boot application and I setup the security config and added one endpoint. I tested that I'm able to hit the endpoint I added and the actuator endpoint locally. However, when deployed on Kubernetes, my app pod is constantly restarting with connection refused for /actuator/info. When I try to hit the endpoint directly (deployed one), I get this strange error: `{...

printing area's of an array on different lines depending on section

so, I've been trying to figure out how to write different parts of an array out to different lines of a txt file for a project that i've been working on. I have tried multiple methods but it usually writes all of the info to one line. I am hoping to print out the different parts of the array without going in and writing out every single variable of the array that I want to have on each line. I can provide the code if needbe to make things easier.

how do I generate POJOs from XSD without XML annotations?

I need to generate a JSON schema within Java application and I've come across few maven plugins which create JSON schema strings from Java classes.

Removing them programmatically using regex and all seems error prone. I want to generate plain and simple POJOs from XSD without any annotations so that they can be used for generating JSON schema. ...

Any ideas? version info: Java: Jetbrains Runtime JDK 21.0.5 Maven: 3.9.9...
