Root Cause Analysis of Excessive Swap Usage in a Spring Boot Project: Native Memory Leak Triggered by MCC Package Scanning

This article details a step‑by‑step investigation of a Spring Boot application that consumed far more physical memory than its 4 GB heap limit, revealing a native‑memory leak caused by MCC's package‑scanning using Reflections and the Spring Boot ZipInflaterInputStream, and explains how configuration changes and newer Spring Boot versions resolve the issue.
