I need more information. Please provide information about what you were doing
to cause the crash. The operating system it occurred on and the crash log that
was written to the jar location after it crashed.

I am using jNativeHook version 1.14 in JavaFx application on Linux Fedora 14
and when jvm crash the log get written in hs_err_pid<processId>.log file like
the following. Due to too long log detail file I have attached the log file :

I used jNativeHook version 1.14 in JavaFx application on Linux Fedora 14 to
capture mouse click and keystroke for every interval of 9-10 minute

Thanks for the error log, can you test version 1.2.0 and see if the error still
occurs? Version 1.1 was shipped without debugging symbols so I would either
need some test code to reproduce the problem or have you reproduce the issue
using the attached jar file and post the log file it generates.

Thanks for your quick reply. I am testing using your attached jar and will post
error log if there is any generated there after.

I have tested with your attached jar file and my application run fine for some
couple of time say 4-5 hours in Linux Fedora 14 and after that my application
get close or exit automatically. I was unable to get error.log file.
I also tested my application by removing the functionality of jNativeHook i.e
without jNativeHook my application run fine. And even others application
running does not get slow and begin to consume less memory.

The same application using jNativeHook 1.1.4 are working fine windows OS and
Mac OS
I have not tested yet using jNativeHook 2 .

I believe the problem you are experiencing was inadvertently addressed by some
refactoring done in version 1.2.

Hi, today I run a simple java program which counting Keystroke and Mouse click
using jNativeHook 1.1.4 in Linux Fedora 14 having RAM 1GB and 2GB swap memory.
The program run find for about 7-8 hrs and after the program exit showing the
following exception
Error: Cannot perform realloc
Is this due to the low memory of my system because I was running numbers of
other application simultaneously Or it is some native issue in jNativeHook.
Please help me

Error: Cannot perform realloc is definitely caused by running out of
memory/swap. The original error described is fixed in 1.2

Hi Remi,
I assume you located the Beta2 download on GitHub because you deleted your
comment? Just in case you can find it here
https://github.com/kwhat/jnativehook/releases/tag/v1.2.0-Beta2
If you would like a nightly, just send me an email directly and I will run it
through the cross compiler for you. I eventually plan to get nightlies
automatically posted somewhere for download.
