Crash after 30 seconds.

[GoogleCodeExporter]

I have a javaFX application that uses the library to detect key events.
When I register the native hook, It take the application 30 seconds ( more or 
less ) to crash. Here is a complete log of the error attached.

Well, I have never seen that error before ;)  What version of the library are 
you using?  If it is 1.1, please try 1.2.  There are a number of nighties 
attached to various bugs or you can just test with beta 2 on github.

If it is still occurring with 1.2, could you provide some test code for getting 
it to crash with javafx?  I am not very familiar with the technology.

Please check the console output for 1.2, there maybe a clue as to what went 
wrong in there.

It's actually occuring only in 1.2, and the console output for 1.2 shows 
nothing special, just the mouse positions when I move my mouse and then part of 
the error log.
I don't beleive it's related to javaFx because it's before I even change things 
in my application. I just load the keyboard driver and register my native hook, 
I start playing with the mouse and it crashes.

I suspect its related to a system property having an unexpected value that 
resulted in some bad math.  I have tested on 10.7.5 32-bit and beta two 
attached to github and I was able to an error that looks like null pointer.

Where did Java dump the hs_err_pid23778.log file for you?

Do you have a scroll wheel mouse?  Does this occur when you scroll?  I cant 
seem to produce an error log even with -XX:ErrorFile, its always empty.

Java dumped the hs_err file in the root folder of my project, the one 
containing src, libs ...

I have a macbook pro with a touch pad, I don't have a scroll wheel mouse. And I 
didn't get the error while scrolling with the two finger touching. It just 
happened when I was moving my mouse.

As far as I can tell it was related to the scrolling in the horizontal 
direction.  Added a check for divide by zero in commit 
4c0e0641f7e53181f49b6fb36573b8847e17190f, and attached a nightly of that build 
here.  Thanks for reporting this one.

Thanks, I'll try it right away and see if it doesn't crash anymore.
