I reported this bug about 2-3 months ago, and people said 
something like it is same in C, and was reported a long time ago 
etc. So, nothing is changing about it.

Not a bug.

This is parsed as - (9223372036854775808L)

That number cannot be represented in signed long, so it fails.

The only correct thing to do is via x3.
