![]() ![]() ![]() Then it is a matter of doing a search through the source code, for example for occurances of "new TreeStructureNode", and then tracking down who created those objects and why they are not being released. You want to look for classes whose instances increase dramatically. VisualVM is very good for doing this because it can compare multiple memory snapshots (via the memory profiler) and show you what changed. The best way to track down a leak is to take multiple heap dumps and see what changed between them. In the VM options field, enter -Xmx1024M. GC Viewer an open-source tool that allows you to easily visualize information produced by JVM. Hold Shift and click the run configuration on the main toolbar. VirtualVM will show you which objects are referencing each byte instance, usally you need to look at only a few instances before a pattern developes.ĭoes the TreeStructureNode declare a byte, or an object that has a byte embedded? You should also look at the next 3 or 4 entries in the list. JProfiler a thread, memory and CPU profiling tool that can also be used to analyze memory leaks and other performance bottlenecks. Though based on the amount of space taken up by the byte instaces, it seem like some object somewhere is storing a lot of byte information (perhaps a StringStream ?). In Java, static fields usually remain in memory as long as the application is running. Excessive usage of static fields can potentially lead to a memory leak. The most common types are detailed below: 1. char and String instances, they are usually the most used instances. Memory leaks can be of various types, depending on how they happen. ![]()
