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.
The Java Virtual Machine (JVM) generates three essential artifacts for performance optimization and troubleshooting: Garbage Collection (GC) log, Thread Dump, and Heap Dump. Each artifact helps analyze memory performance, thread states, and memory allocation issues. Various tools assist in generating and examining these artifacts, aiding in effective problem resolution.
Heap dump is a snapshot of the Java memory. It contains information about the Java objects and classes in the heap at the moment the snapshot is triggered. It’s vital artifact to diagnose any Java memory related problems.
