StackOverflow recommends BigInteger and doesn’t talk about inefficiency.
Starting with BigInteger now, it should be fairly straightforward to refactor into a different class with the same API later (ie simple search & replace on
the name BigInteger and the import statements for its package). That is, only if performance measurement shows that it’s in fact a problem.
Or are you concerned that the API of BigInteger is already inefficient ? – Are you concerned about memory size or performance ?
Thanks,
Martin

I would hope we can simply use the BigInteger for now even though its inefficient. But at least this stuff would
work. At the same time we can look into a more solid solution.
Good opportunity for somebody to contribute one.

Oh, I see. I didn't notice the bug number in the subject. Do you know of an open source Java implementation of 128-bit integers with EPL-compatible license? I'd like to
avoid BigInteger since it's too heavy and inefficient.

Thanks. I already filed a bug and the ID on the subject. Do you want me to create another one?
I wonder what is the outlook for the bug, my code needs this thing to work.
This is most likely caused by the fact that ULONG_MAX cannot be represented by a Java long. Could you please file a bug.

It seems to be a bug in eclipse. I created a bug last month. Can someone please help and confirm
if this is an eclipse bug? and/or will it be fixed shortly?
Thanks a lot, my code heavily relies on this to be working correctly...
