>Number: 118735 >Category: java >Synopsis: Java 1.5: JMX OperatingSystem mbean yields wrong results >Confidential: no >Severity: non-critical >Priority: low >Responsible: freebsd-java >State: open >Quarter: >Keywords: >Date-Required: >Class: sw-bug >Submitter-Id: current-users >Arrival-Date: Sat Dec 15 23:00:06 UTC 2007 >Closed-Date: >Last-Modified: >Originator: Kees Jan Koster >Release: 6.3-PRERELEASE >Organization: >Environment: Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-p4-kjkoster_15_may_2007_13_43) Java HotSpot(TM) Client VM (build 1.5.0-p4-kjkoster_15_may_2007_13_43, mixed mode) >Description: The OperatingSystem mbean returns no useful results for the attributes that I tested, which were: TotalSwapSpaceSize, FreeSwapSpaceSize, OpenFileDescriptorCount, FreePhysicalMemorySize, CommittedVirtualMemorySize, MaxFileDescriptorCount, TotalPhysicalMemorySize. These values are either seemingly random, or fixed at some unless value. >How-To-Repeat: Start a Java program using FreeBSD's 1.5 Java port. On the command line, enable JMX using the options: "-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false". Then use jconsole to attach to this process and view the mbean identified by java.lang:type=OperatingSystem. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
