What replaced PermGen in Java 8?
Track: Java
Topic: JVM Architecture
Focus: Metaspace
Java: Metaspace
Answer
Metaspace replaced PermGen. Frame the concept in practical terms so you can explain it during interview discussion.
In Java 8, PermGen was replaced by Metaspace, shifting class metadata storage to native memory. This transition resolved many issues related to fixed memory size constraints, enabling more flexible memory management. For example, applications with varying class loading patterns now benefit from reduced risk of memory errors.
