FULL PRODUCT VERSION :
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_04-b05)
Java HotSpot(TM) Client VM (build 1.5.0_04-b05, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
SunOS mary 5.9 Generic_117171-07 sun4u sparc SUNW,Sun-Blade-100

A DESCRIPTION OF THE PROBLEM :
java.lang.management.ThreadInfo.getWaitedTime and java.lang.management.ThreadInfo.getWaitedCount do not take Thread.sleep in account, which contradicts the specification of these methods. For instance:

getWaitedCount:
"Returns the total number of times that the thread associated with this ThreadInfo ... has been in the WAITING or TIMED_WAITING state."

TIMED_WAITING: "Thread state for a waiting thread with a specified waiting time. A thread is in the timed waiting state due to calling one of the following methods with a specified positive waiting time: Thread.sleep ..."

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile and run the program below

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
2000-0=2000 (or any number near 2000)
2-0=2
ACTUAL -
1011-0=1011
1-0=1


REPRODUCIBILITY :
This bug can be reproduced always.
