The content discusses troubleshooting OutOfMemoryError using the Eclipse MAT tool. It highlights best practices and tips for effectively debugging memory issues. A video tutorial is available for a more in-depth understanding.
Eclipse Memory Analyzer (MAT) is a tool for heap dump analysis, featuring 'incoming references' and 'outgoing references'. Incoming references are objects that reference a particular object, while outgoing references are objects that are referenced by it. The article illustrates these concepts with a sample application, clarifying their differences.
Procedures to diagnose and solve all the 5 types of OutOfMemoryErrors that happen within the JVM heap are same. In this article, let's explore how to diagnose these 5 types of OutOfMemoryErrors.
