Since 1.5 the OutOfMemoryError object contains a descriptive reason:



try
        {
            OOM(); //too much memory is being allocated in here
        }
        catch (OutOfMemoryError oome)
        {
            System.err.println(oome);
            Runtime.getRuntime().halt(1);
        }


1.5 gives this:

java.lang.OutOfMemoryError: Java heap space

while for 1.4.2 the same is less informative:

java.lang.OutOfMemoryError


It would be nice to backport the 1.5 functionality to 1.4.2 if it's
not too complex.
