Play the bad JVM very simple--tostring recursive call

A memory overflow situation is rare under the JVM's memory management mechanism. At least I met less, as if I had been in ssh several times when I published the project. Today saw a very simple way to make memory overflow (well, I seem to be dead--! ）：

1  Public classinfiniterecursion {2      PublicString toString () {3         return"Infiniterecursion Address:" + This+ "\ n" ;4     }5      Public Static voidMain (string[] args) {6Infiniterecursion demo =Newinfiniterecursion ();7 System.out.println (demo.tostring ());8     }9}

The problem with the above code is the recursive invocation of the ToString method, and when the compiler finds a string with a plus sign followed by an object, it converts the object to a string by default, The method is to invoke the ToString method of the object (note: The Java object must have the ToString method), and then there is infinite recursion.
