Eclipse Memory analyzer (MAT) is used to analyze memory leaks in your application. If an object has no reference, it is released by Java Garbage Collector. In a situation you get OutOfMemoryError, you can instruct Java Virtual Machine to create heap dump. The Eclipse Memory Analyzer provides a visual image of Java heap dump and helps to identify memory leaks. Use the following command to guide JVM to create a heapdump.
