Hi, When I execute my program (a simple window) with the JRE, and when I close it immediatly, I don't find the initial memory on my computer any more. I loose 20000 Ko every time I lauch it ! This is mean because if I launch the program several times, I haven't any virtual memory any more. Could anyone explain me why the JRE doesn't deallocate entirely the allocated memory after having executed the program ? Thanks in advance.
