Subject [jira] [Commented] (LUCENE-7933) LongBistSet can't have Long size

Won Jonghoon commented on LUCENE-7933:
--------------------------------------

  You say "This class is for supporting a contiguous (simple) bitset up to 64*2^31 bits in size."

but it doesn't check max size.




LongBistSet maxLongSizeLongBistSet = new LongBistSet(Long.MAX); ===> no error because
no size check, numBits can have the value that is greater than 64*2^31. example  (2^63 -
1)





I think LongBitSet class is for supporting a contiguous (simple) bitset up to Long.MAX
bits in size.

Well I will make new class using BitSet class  that is a java stand API.

It's not clear to me where you think the bug is, but perhaps you could provide a patch that would clear it up?

> private final long[] bits; // Array of longs holding the bits 
> ===> bits.length is small for bit number having Long.MAX
