I have a new problem: :-)
What does the statistic in the appendix mean? It says that there are 82.8% of
22528KB free???
1. But when I try to allocate 22 100000B arrays it says that it has a
   memory error...
2. But 3879KB of 22528KB are much less than 17.2%.

Can somebody explain me this statistics, please?
Can somebody tell me hoe I could use the memory more efficient, please?


<GC: heap 22528K, total before 3879K, after 3879K (104422/104422 objs)
