Yes, I know that's not the same thing, sorry for abusing of "id est"
abbreviation. BTW, since I've CC people not used to "openjdk" ecosystem, I
prefer to talk about openjdk than icedtea, is this a problem ?

Right now, main backports from bsd-port branch are :
- jdk/src/solaris/native/java/net/NetworkInterface.c (small changes in structs
- jdk/src/solaris/native/sun/nio/ch/FileChannelImpl.c (sendfile from kfreebsd)
- hotspot/src/os/linux/vm/attachListener_linux.cpp (LOCAL_PEERCRED instead of

Because I thought (naively ?) that since Zero doesn't use any
assembly/linux/gcc specific hacks it should be easier to port to GNU/kFreeBSD
as a first step.

Could you explain a little bit more why do you think zerovm can add
complexity/errors to my porting work ? You think that it would be simplier to
work on porting to Hotspot ?
Right now, building bsd-port give a lot more errors since :
- it expect a *BSD userland (whereas GNU/kFreeBSD has **GNU tools**)
- it expect a *BSD libc (various diff from **GNU glibc**)
- large part of source code is a copy/paste from linux directories (lots of
duplicated code) so patches from icedtea are not applied...
But maybe you're right, I'll try the other way around : I'll try to adapt bsd-
port to GNU/kFreeBSD.
