Using JDWP commands ObjectReference.GetValues and ObjectReference.SetValues for static fields results in not changing fields values and jvm crash (SIGSEGV) in product build.
Product build is crashed stably on Windows and intermittently on Linux

Fastdebug VM build stably crashes with the following assertion:
# A fatal error has been detected by the Java Runtime Environment:
#
# Internal Error (/BUILD_AREA/jdk7/hotspot/src/share/vm/prims/jni.cpp:175), pid=12827, tid=2910305168
# Error: guarantee(jfieldIDWorkaround::is_instance_jfieldID(k, id),"must be an instance field")
#
# Java VM: Java HotSpot(TM) Client VM (13.0-b02-fastdebug mixed mode linux-x86 )

The failure is reproduced at least with latest 6u6, 6u10, jdk7, both product and fastdebug bits.
