Generate java dump when OutOfMemory

Question

I have a program that should eventually generate OutOfMemory . The program code is:

public class VeryLargeObject implements Serializable {
    p         


        

Answer 1

I suspect the jvm could not write to the path and fails silently. For example, this has to be a file name in a directory which exists. If you have a directory D:\workspace it will fail. If you have D:\workspace\heap.hprof it may work. Try creating a blank file of that name first to see you can do this.
