Always leads to OutOfMemoryError when we use large scalar random keys

[xfeep]

        Map<Long, Object> map = new NonBlockingHashMap<Long, Object>();
        for (long i = 0;;i++) {
            map.put(i, i);
            map.remove(i);
        }

Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

It is really serious bug because this make it unusable in many cases.

Same issue was addressed at

1. https://sourceforge.net/p/high-scale-lib/bugs/14/
2. http://jsr166-concurrency.10961.n7.nabble.com/Unexpected-memory-usage-in-NonBlockingHashHashMap-td9913.html

In the README file please add some notices about its limitation .

This problem is serious, how can I avoid it?

i just got on my feed, you should never do this, this is not a bug. why would someone want to add something and remove it?

In some hot operations, this is indeed the case
