JDK-8364518 introduced suport for Job Objects in os::commit_memory_limit() and included a warning log message if information about a job object could not be queried. This causes a lot of warnings to be printed due to "Access is denied". Some tests are failing on Windows when these warning are printed:
sun/rmi/runtime/Log/6409194/NoConsoleOutput.java
java/lang/IO/IO.java
A number of java/lang/ProcessBuilder/ tests

Example warning output:
Java HotSpot(TM) 64-Bit Server VM warning: Attempt to query job object information failed: Access is denied
