When attempting to re-project a Map, comprised of three shape file layers, to a UTM projection the map went blank. I had two other maps in the background, one comprised of WMS Layers and the other of shape layers. All maps went blank. I was still able to perform operations such as "Zoom to Layer Extent", "Pan", "New Wizard dialog". However, maps stayed blank. Error log indicated an OutOfMemory Error in the the renderer. It appears to be an unrecoverable error for the renderer yet the application continued to function as if everythink was working fine. !ENTRY org.eclipse.ui 4 4 2005-01-26 11:18:36.253 !MESSAGE Unhandled event loop exception !ENTRY org.eclipse.ui 4 0 2005-01-26 11:18:36.253 !MESSAGE Java heap space !STACK 0 java.lang.OutOfMemoryError: Java heap space !ENTRY org.eclipse.core.runtime 4 2 2005-01-26 11:18:36.253 !MESSAGE An internal error occurred during: "Composite Renderer Rendering". !STACK 0 java.lang.OutOfMemoryError: Java heap space
