🍃 Who replaced a third-party dependency with a Spring HTTP Service Client and is happy about it? 🙋♂️
In Spring Batch Notion, access to the Notion API was done via Notion SDK JVM, a Kotlin library that abstracts the REST communication. While it’s charming for a quick start, it has a few drawbacks:

Instead of buying more stuff that I don’t really need, I’m sponsoring open source #Java projects that I rely on, starting with #JUnit and #AssertJ (via core maintainers Joel and Stefano).
If I was a big company using Java, I’d be embarrassed at not sponsoring these projects.
