[Ikvm-developers] IKVM and JNI

[Дейзи Ч. <dai...@ma...>]

Hi Jeroen,
thanks for quick answer. Your suggestion regarding -Xcheck:jni looks very bright, because we DID use it for some time - the problem was that JRE5.0 worked fine with our dll, but JRE6.0 (updates 0-7) crached with hotspot log. But with -Xcheck:jni option it worked fine (Sun's bugs database said, that dlls compiled with Borland compiler don't save and restore on exit some FPU control word and recommended using this option). 
I didn't find now that exact bug, but these ones seem very similar:

http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6487931

Fortunately, they admitted this as JVM fault, and since JRE 6.0 update 10 the problem disappeared!
Hope this helps - maybe there is something like that in IKVM code?
