I compared the performance of this generics map to a simple integer list.
The map was much slower and it also ate huge amouts of memory, > 1.5 GB.
Strange. My data is only some kilobytes, not gigabytes.
The code runs in parallel threads. Could that be a problem?
Anyway, I will look for some other lookup methods now...
