[9] RFR 8163518: Integer overflow in StringBufferInputStream.read(byte[], int, int) and CharArrayReader.read(char[], int, int)

[Ivan Gerasimov]

Okay, I simplified that confusing part of the fix and made a minimal 
change to minimize chances of any unintended changes in behavior.

Is it good to push now?

Btw, that @requires (os.simpleArch == "x64" & os.maxMemory > XX) logic 
works quite well.
I've seen that on different hosts one, two or all three tests were run, 
depending on the environment.
I think, we may consider enabling some of the memory-demanding tests 
that are currently ignored.

With kind regards,
Ivan
