¿Cuál podría ser la posible causa de las pérdidas de memoria en Java?

What could be the possible cause of memory leaks in Java?

In general, a Java memory leak happens when an application unintentionally (due to logical errors in code) holds on to object references that are no longer required. These unintentional object references prevent the built-in Java garbage collection mechanism from freeing up the memory consumed by these objects.

One of the core benefits of Java is the automated memory management with the help of the built-in Garbage Collector (or GC for short). The GC implicitly takes care of allocating and freeing up memory and thus is capable of handling the majority of the memory leak issues. Memory leaks are a genuine problem in Java.

Memory leak occurs when programmers create a memory in heap and forget to delete it. To avoid memory leaks, memory allocated on heap should always be freed when no longer needed.

One of the core benefits of Java is the JVM, which is an out-of-the-box memory management. Essentially, we can create objects and the Java Garbage Collector will take care of allocating and freeing up memory for us. Nevertheless, memory leaks can still occur in Java applications.

Diagnosing Leaks Identify Symptoms. As discussed, in many cases, the Java process will eventually throw an OOM runtime exception, a clear indicator that your memory resources have been exhausted. Enable Verbose Garbage Collection. One of the quickest ways to assert that you indeed have a memory leak is to enable verbose garbage collection. Enable Profiling.

3.1. Memory Leak Through static Fields. The first scenario that can cause a potential memory leak is heavy use of static variables.
