![]() Both the SDL and the SDL2 builds crash in the same way. The code can be linked to either SDL 1.2 or SDL2 and also uses some boost stuff. There is a common problem in all links just the way of explaining may be different. As a consequence, with the exception of the Expression component. I encounter Null pointer exception when using BeforeTest, BeforeMethod and trying to run two classes from testng.xml Hopefully, you must have got some idea of the problem defined in the above links. ![]() In this case, the only possible variable. A projector hides attributes from preceding components all succeeding components can. I can mount it from the pi or the Win10 laptop. The error in the log is null pointer exception, which means you tried to use a variable which wasnt initialised. I run a very old clone of an XP laptop in a VMWare VM, share a directory and mount that from Ubuntu. What should I look for? Everything else in Ubuntu runs just fine. It must be a hardware issue of some sort because the exact same code compiles and runs fine in Win10 and on a Raspberry Pi. But after I removed those sticks the crashing is still happening. I did a mem test from the boot screen and the 2x4GB test ok. That's never been a problem for about 5 years. I have an AMD 8 core CPU and 24GB of ram in the form of 2x4GB and 2X16GB The 2x16GB says each stick is 2x8GB so I would think I'd be getting 32GB from these two, but I don't. Then I compiled a much older version of LaserBoy and it does the same thing. So first I thought this was some new bug I had introduced into the code. Team Name: Null Pointer Exception Team Members: Ankit Aryal, Lindsay Cason, Yinghao Lin, Owen Sutka, Eboni Williams Advisor: Dr. The app crashes in all kinds of different places but it all seems to lead back to malloc.c and free being called on an invalid pointer. I don't know much about gdb, but I have found some stuff online and I can get it to save a core dump and use gdb to do a back trace. (obviously, only the else Nothing is ‘important’).I've been developing an SDL or SDL2 app called LaserBoy for many years on Ubuntu with no major issues, but now, all of a sudden, it's crashing. ![]() In Haskell, there is the Maybe monad which facilitates chaining “partial” computations together without Haskell which does not have that notion of null values and theĬorresponding Nullpointer exception. In short, NullPointerException is thrown when a program attempts to use an object reference, which has the null value. The funny thing is that I recently wrote similar code myself thatĪlone would not be a surprise yet, but I actually wrote it in In fact, NullPointerException is a RuntimeException. That this obviously touches upon the question if you should avoid ![]() Saying that things are not what they are supposed to be. together a set of components providing a great starting point to evaluate a. How people feel when they try to reason about an object being nullĪnyway, spotting an else return null I always get a bad gut feeling Projector Control File for the Chosen Chipset. Various control structures in an endless method and you surely get an idea To make things more familiar, in Version 2 you could imagine multiple return null lines hidden in public class NullPointerException extends RuntimeException Thrown when an application attempts to use null in a case where an object is required. Version 1 if ( password = "12345" ) return valuableTreasure else return null // or, equivalently // Version 2 if ( password = "12345" ) return valuableTreasure return null
