    copied!<p>I have a problem regarding an actual project using Java, Kinect (OpenNI) and Processing.<br> If I use just Processing and Java everything works fine nothing is stumbling and I get no exceptions.<br> But if I jail the processing Applet in a JFrame (to solve some problems with the Applet Style of Processing) I got the following problem: </p> <ul> <li>Every 3 seconds the kinect images hangs shortly (looks like Java is clearing anything out of the memory using the garbage collector) </li> <li><p>after 20 seconds the application stops and I get the following error:</p> <pre><code>Exception in thread "Animation Thread" java.lang.OutOfMemoryError: Java heap space at java.awt.image.DataBufferInt.&lt;init&gt;(Unknown Source) at java.awt.image.Raster.createPackedRaster(Unknown Source) at java.awt.image.DirectColorModel.createCompatibleWritableRaster(Unknown Source) at java.awt.image.BufferedImage.&lt;init&gt;(Unknown Source) </code></pre></li> </ul> <hr> <p>Here is my relevant Code regarding the visualization:</p> <pre><code>public boolean drawGrayscaleImage(){ //init PApplet and build JFrame GrayscalePApplet grayscalePApplet = new GrayscalePApplet (); grayscalePApplet.init(); this.grayscaleJFrame = this.initFrame(grayscalePApplet); //Set Uplink for PApplet and begin drawing grayscalePApplet.setGraphicP(this); return false; } </code></pre> <hr> <p>Here the drawing function from the Processing PApplet Class</p> <pre><code>public void draw(){ if(graphicP != null){ //creat the relevant image Buffers for java and Processing BufferedImage image = new BufferedImage(imageWidth, imageHeight, BufferedImage.TYPE_BYTE_GRAY); PImage pimage = new PImage(image.getWidth(),image.getHeight(),PConstants.ARGB); //fill up the databuffer using a converted Kinect Grayscale Image DataBufferByte dataBuffer = new DataBufferByte(graphicP.getImage(ImageType.GRAYSCALE), this.imageWidth * this.imageHeight); Raster raster = Raster.createPackedRaster(dataBuffer,imageWidth, imageHeight, 8, null); image.setData(raster); //draw image to Processing image.getRGB(0, 0, pimage.width, pimage.height, pimage.pixels, 0, pimage.width); pimage.updatePixels(); image(pimage, 0, 0); // null everything to get Garbagecollection to work (?) image = null; pimage = null; dataBuffer = null; } } </code></pre> <p>How can I prevent that OutOfMemory Exception?<br> What may causes that exception? </p>
