Mitteilung Hi! When I try to implement the XboxController library into my game, it works for a little while, but after a short time crashes and leaves a log. Here's the top part of the log:

# A fatal error has been detected by the Java Runtime Environment:
# EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x00000000021fe959, pid=9440, tid=2148
# JRE version: Java(TM) SE Runtime Environment (7.0_55-b13) (build 1.7.0_55-b13)
# Java VM: Java HotSpot(TM) 64-Bit Server VM (24.55-b03 mixed mode windows-amd64 compressed oops)
# Problematic frame:
# J sun.misc.FloatingDecimal.readJavaFormatString(Ljava/lang/String;)Lsun/misc/FloatingDecimal;
# Failed to write core dump. Minidumps are not enabled by default on client versions of Windows

I love your implementation and have already written it into my program, but this crash is very frustratingly making it useless :( I'll likely have to go to another implementation if unable to work this out.

Thanks for the help, hope you see this.

Mitteilung Thanks for your forum request. I am sorry that you have troubles with my XboxController library. If a sporadic crash is always hard to fix. Try the following:

- I seems that the error is due to a bad conversion of the kind

Double aDouble = Double.parseDouble(aDoubleStr);

I checked my libraries, but I couldn't find this conversion anywhere. Check if you never mix integers and doubles in your code

- Use the full constructor
* Creates a XboxController instance using the given native Windows DLL
* and tries to establish a connection to the controller with the given
* player number.
* @param dll the fully qualified path to the native DLL.
* If the extension .DLL is missing, the DLL is searched in the Windows path.
* @param playerNb the number of the player 1..4
* @param controllerPollPeriod the period (in ms) of the native timer that polls the state of the controller
* @param queuePollPeriod the period (in ms) of the Java timer that polls the message queue
public XboxController(String dll, int playerNb, int controllerPollPeriod, int queuePollPeriod)

and set the controllerPollPeriod and queuePollPeriod to a value greater than the defaults (greater than 50 ms).

- Use the source of XboxController and set the private boolean debug = true. Check what is written to the console, when the crash happens. You also may write debug information to a log file.

-Isolate the code fragment where you think that the crash happens and send it me.

Hope this helps.
