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

Could I add my small comment? The bug shows up not only after calling JNI_CreateJavaVM, but just on using any dll, compiled by Borland C Builder.

Yes, with JRE1.5.0 the same code works fine, and after adding -Xcheck:jni for 1.6 - it works also and gives the same warning as in the bug description, so I decided not to post it as a separate bug.

Here is my hotspot log:
