Tests script problem.

Two runtime regression tests fail on Windows when run with debug VM:
closed\runtime\4474873
closed\runtime\4524377

fastdebug\bin\java -Xcheck:jni CheckJNITest InstanceFieldID2
#
# An unexpected error has been detected by Java Runtime Environment:
#
#  Internal Error (C:\PrtBuildDir\workspace\src\share\vm\prims\jni.cpp:181), pid=21032, tid=12644
#  Error: guarantee(klass_hash_ok(k, id),"Bug in native code: jfieldID class must match  customer ")
#

Test's script exptects "FATAL ERROR" which produced only by product VM:

C:\hs_regression\Test4474873>C:\jdk7_b12\bin\java -Xcheck:jni CheckJNITest InstanceFieldID2

N/A

The negative test runtime/4474873 tests access to java fields from native code and the bug is all about that in fastdebug we hit guarantee (see Synopsis) before checking the validity of jFieldID. So such check was added which throws exception that is expected.  Webrev at http://jruntime.east/~ik199011/my_webrevs/6589875_7.0_webrev/
