        Description

        FULL PRODUCT VERSION :
        java version "1.6.0"
        Java(TM) SE Runtime Environment (build 1.6.0-b105)
        Java HotSpot(TM) 64-Bit Server VM (build 1.6.0-b105, mixed mode)

        #1 SMP Tue Aug 29 10:40:40 UTC 2006 x86_64 x86_64 x86_64 GNU/Linux

        A DESCRIPTION OF THE PROBLEM :
        When limiting the available CPUs by Linux 'taskset' command, JVM obeys this limitation but Runtime.availableProcessors() always returns the number of CPUs where the hardware has.

        This bug can be reproduced always.
