Description
The jtreg test failure of

hotspot/test/compiler/floatingpoint/Test15FloatJNIArgs.java

is caused by incorrect floating point argument handling in JNI native wrapper.

The following patch:

http://people.linaro.org/~ningsheng.jian/jni-fix/webrev.00/

can fix this bug.

I also updated the test case (and renamed to TestFloatJNIArgs.java),
which exposes more issues in jni floating point args handling. (Need
to update the fake bug-id in the test java source, as I don't have
access right to JBS). Those issues can also be fixed by the patch.

Could someone please help to review and process the patch?
