The application, when starting back, is initializing the JVM properties.
-XX:+HeapDumpOnOutOfMemoryError , -XX:HeapDumpPath and -XX:+PrintHeapAtGC are the JVM arguments used for the application in the properties.xml and upon starting it, which ensure that any time there is an OutOfMemory error, an automatic heap dump will be created in this specified directory.
When you have an OutOfMemory, you will see in app-system a note: "Heap dump file created" or "java.lang.OutOfMemoryError: Java heap space "
