Just now I got an out of memory error after making quite some chances to 20.000 songs after which Jaikoz just exits. Not funny
That is bad luck.
Once Out of memory its too late, we cant safetly handle this. In an earlier version of Jaikoz I did monitor memory usage, and issue a warning when memory was low, however this proved to be unreliable and would sometimes issues warnings when there was more heap memory available than had been allocated. But this was with java 1.4, it may work better with java 1.5.
