Java HotSpot Virtual Machine

If I try to run my JavaAppl, I always get the following message. Something seems to be wrong with the operation call uread() of the Library foxapi.lib. If I disable this operation (with //), I get the Defaultvalue=5 back. So the jni seems to work. But what's wrong with this operation?? In a C++-Prog this Operation doesnt's make any problems. I often use the foxapi.lib and it works well.

Any idea?

Thanks Patric
