I basically have a program that filters records from one excel file to another excel file using the apache poi. My program runs fine when it runs using netbeans. However, upon doing a clean and build and double clicking the .jar file inside the dist folder, it runs for very long( too long!) and gives me the following error( that I got by running the program from command prompt ).

Is there any work around for it? I have already increase the heap size to be -Xms1500m inside netbeans before cleaning and building.
