What does "[C", "[B" "[J" classnames mean in

Hi,
I ran the jrcmd tool to get some memroy diagnostics and "[c" class name occupies the most.
--------- Detailed Heap Statistics: ---------
                      51.5%     98k      890    +98k[b] [C[/b]

What does "[C", "[B" "[J" classnames mean in Detailed Heap Statistics? How can I find them in my code ?                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           

Generally speaking, the allocation traces from JRMC would show where objects are allocated. However, objects such as String, char[], byte[] etc are so ubiquitous that they are very hard to trace.
Your best bet could be to focus on application specific packages and look for unusual object counts.

    Welcome to the Apple forums.
    Good idea to fill out your profile so people can see what machine you are writing about.    
    Also a good idea to do a little research through the 'More like this' panel to the right of your initial post.    Each of the threads also contains more leads so it is amazing how much you can learn from them.
    Good hunting.

  • HT1338 What does a medium write error mean, when trying to burn a cd?

    What does a medium write error mean, when trying to burn a cd?

    nwalls wrote:
    What does a medium write error mean, when trying to burn a cd?
    It's an error message returned by the burner. You can see the full list of these error messages here
    <http://en.wikipedia.org/wiki/Key_Code_Qualifier>
    It's not specific enough to pinpoint what caused it—it could be anything from a bad optical medium (CD-R) to a dusty or dying laser diode. You have to isolate the problem—use a different CD-R brand, try a different speed, use a different burn engine (eg, Burn), etc. If it occurs once or twice, randomly, it's more likely to be a bad disc. If it occurs consistently, and at the same stage of the burn process, it's more likely to be a drive or software issue.

    Open AirPort Utility, the application that you used to configure the AirPort Express and click Manual Setup.
    Click directly on the word "Status" (2nd line) and a window will open to tell you why the Express is complaining. What is the message?
    It might be a notification that an update is available for your Express.

  • What does error -50303 and -50016 mean ?

    Does anyone know what does error -50016 and -50303 mean ? Can you tell me how to solve it ? I am using scxi 1161 for my application and i am getting these error codes.

    Hi Anku
    You can find explanations to error codes in labVIEW by going to the Help menu and selecting Explain Error and then inputing the error codey you get. You can also right-click in the error node in you program that presents this error and choose "Explain error". The two error codes you have posted have the following explanations:
    -50016:
    "NI Platform Services:  The specified window type is not valid or is inappropriate in the context of the current device configuration. The operation could not be completed as specified."
     -50303:  
    "NI Platform Services:  The specified device could not be initialized. The operation could not be completed as specified"
    Does both of these error occur in the same attempt to run or at different attemps to run the code? In which order are you getting these errors if they appear at the same time? The second error code indicates that you either don't have a connection to your instrument, that it's not configured correctly (such as the first error indicates) or that the instrument is not functioning as it should. The first error is a configuration error and could also be a result of the second error (i.e. no connection or broken instrument). So as both error codes you are getting could be a result of the other it is important to note which occurs first.
