Fatal error: Failed to write core dump

问题

I'm trying to run the unit tests in the tess4j distribution currently. And while running one of the unit tests, java crashed with the following error:

TessBaseAPIGetIterator
#
# A fatal error has been detected by the Java Runtime Environment:

Can i please get help? i'm fairly sure that the DLL file is not corrupt and neither is my harddisk. i'm using the Windows 8 OS and the latest version of eclipse to build the project.
