This post focuses on the trace generated by Java VisualVM. Traces can come in different formats, as they can be generated by different Java memory leak detection tools, but the idea behind them is always the same: find a block of objects in the heap that should not be there, and determi...
In this tutorial, we created a memory leak for educational purposes and discussed various detection techniques, including logging, profiling, verbose garbage collection, and heap dumps. Each method offers valuable insights into an application’s runtime behavior and memory consumption. Logging helps iden...

The VM now provides automatic container detection support, which allows the VM to determine the amount of memory and number of processors that are available to a Java process running in docker containers. It uses this information to allocate system resources. This support is only available on Linu...
