Name

java-gco-ref - Java-Land GC Object Reference Flame Graph

This analyzer profiles garbage collection object references in Java-land code execution within JVM applications. It captures the reference chains and allocation sites of heap objects managed by the garbage collector. The analyzer generates flame graphs that visualize object reference relationships and memory consumption patterns, helping identify memory leaks, excessive object retention, heap memory issues, and memory optimization opportunities in Java applications.
