STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Simply use FlightRecorder with any Java application on Windows 7 64 Bit with JRE 7u45, options don't matter.

EXPECTED VERSUS ACTUAL BEHAVIOR :
I would epxect that CPULoad is available in FlightRecorder, as it is in JMX Console. But it is not in FlightRecorder, instead following trace info is logged: Unable to generate requestable event CPULoad
ERROR MESSAGES/STACK TRACES THAT OCCUR :
Unable to generate requestable event CPULoad

REPRODUCIBILITY :
This bug can be reproduced always.
