hey.. whenever i create a mxj object, mxp suddenly shutsdown..

did this happen to any of you? is there a way to fix this bug?

Process 1.83 GHz Intel core duo (Memory - 1Gb 67 MHz DDR2 SDRAM)

I also noticed this error on my windows machine:

Intel Core2 CPU 6600 at 2.4 GHz (Ram - 1gb)

I was able to work around by copy pasting a bit of code.. compiling and testing as i copy/pasted. But i have to get this working on the mac machine, and the copy/paste method isn't an option on the mac machine because it continues to crash.

Mac OS X on a Mac Mini machine.
version 10.5.5
Process 1.83 GHz Intel core duo (Memory - 1Gb 67 MHz DDR2 SDRAM)

Very strange. Can you run other java programs, from class files of applets?

For instance, try to compile and run this program:

public class Hello {

    public static void main(String[] args) {
        System.out.println("Hello world!");
    }
}


What do you mean here? Did you successfully create and use an mxj object? Then mxj and your java virtual machine should be OK and the error is probably in your code.

Btw, the java version on your mac is out of date. You can download the latest version from

i was able to copy/paste the code from the crashy mxj object and paste it into the new mxj object as i compiled and tested each section of code..

I opened the java source, and edited, and compiled it.

I repeated this process as i was adding and testing more code... at which point the crash happens. and there's no going back.. so i end up creating a new mxj quickie object and repeating the process.

oh, you're right about the java version.. i'll update it and see what happens

Oh then I misunderstood you. Its always good to be specific, "whenever i create a mxj" may lead others to think you experience a crash on upon creating 

Your JVM is probably alright then, though upgrading it does no harm. If you post the code for your java object we might be able to help you further.

I attached the entire java program here..

This program is supposed to read the file-name (the file is in the same folder) and print the captions on the screen. The program reads through the entire .srt file and sets up the timings and captions to print, and the function execute() takes care of updating the clock and displaying captions on the screen.
