I developed an application in C++ to import .DWG files(Autodesk's drawing file). The application is invoked in Java via JNI. Sometimes, the java application closes it self suddenly by an error:
# A fatal error has been detected by the Java Runtime Environment:
# Internal Error (os_windows_x86.cpp:114), pid=4280, tid=2324
# Error: guarantee(result == -1,"Unexpected result from topLevelExceptionFilter")
# JRE version: 6.0_14-b08

It doesn't happen for all dwg files, just for some of them. I found it was caused by the lack of some DLLs. If I added the path which contains all DLLs from Autodesk to java.library.path, there won't be any error. There're over 100 DLLs and I don't want to put all of them into my application.
My application(a DLL file) can be loaded without any problem by Java, so my first question is: when the DLL is loaded, doesn't Java check all dependent libraries for the DLL?
My second question is: Is there a way to catch this error in my C++ code? Java crashes suddenly is too unfriendly for users. I tried using catch(...), but nothing could be caught.
