![]() ![]() The first scenario that might cause a Java memory leak is referencing a heavy object with a static field. Static Field Holding On to the Object Reference These parameters specify the initial Java Heap size as well as the maximum Heap size. That’s why, when starting our application, we can adjust the JVM to suit our memory needs: -Xms -Xmx Credits: viniciuslrangel and Forge, that help-me a make this mod. In this initial section, we’re going to focus on the classic memory leak scenario – where Java objects are continuously created without being released.Īn advantageous technique to understand these situations is to make reproducing a memory leak easier by setting a lower size for the Heap. So, let’s have a focused look at some of the standard practices of preventing memory leaks, by analyzing some common scenarios. A number of tools perform static analysis to determine potential leaks, but these techniques aren’t perfect because the most important aspect is the actual runtime behavior of the running system. Referenced objects won’t be collected, even if they’re actually not longer used by the application.ĭetecting memory leaks can be difficult. As a result, the application consumes more and more resources – which eventually leads to a fatal OutOfMemoryError.įor a better understanding of the concept, here’s a simple visual representation:Īs we can see, we have two types of objects – referenced and unreferenced the Garbage Collector can remove objects that are unreferenced. The standard definition of a memory leak is a scenario that occurs when objects are no longer being used by the application, but the Garbage Collector is unable to remove them from working memory – because they’re still being referenced. We’re also going to use the Java YourKit profiler throughout the article, to analyze the state of our memory at runtime. In this article, we’re going to describe the most common memory leaks, understand their causes, and look at a few techniques to detect/avoid them. Nevertheless, memory leaks can still occur in Java applications. ![]() Essentially, we can create objects and the Java Garbage Collector will take care of allocating and freeing up memory for us. One of the core benefits of Java is the JVM, which is an out-of-the-box memory management.
