Java HotSpot(TM) Server VM warning: increase O_BUFLEN in ostream.hpp -- output truncated

[Ulf Zibis]

Thanks for looking at 6916395.
All 4 "guys" of db(), qb() have been inlined in the 2 encode() methods, 
but only three of them were printed separately. So I'm confused, why 
only 1 of them is missing.

Can you give me a hint about -XX:PrintAssemblyOptions=hsdis-print-bytes ?
What is the purpose of it,
and if/why it is mandatory to get a correct PrintCompilation output?

-Ulf
