FULL PRODUCT VERSION :
Java VM: Java HotSpot(TM) Client VM (1.6.0-rc-b104 mixed mode, sharing)

FULL OS VERSION :
Windows 2000 Pro SP 4 [5.0.2195] German

A DESCRIPTION OF THE PROBLEM :
All I do is calling JNI_CreateJavaVM()
With -Xcheck:jni enabled I got the following warning:
Java HotSpot(TM) Client VM warning: Floating point control word changed by nativ
e JNI code.

Without Xcheck:jni enabled the VM crashes with the following info in the hs_err_pidXXX.log file.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Just call JNI_CreateJavaVM

Attached is the test program to reproduce the warning. It��s written in Delphi but there should no difference to C/C++ cause it��s very simple and calling the JNI_CreateJavaVM() from JVM.DLL only. The source is inlcuded and documented.

It��s a simple Console application
