As the build docs state, you need a working version of Java in order to
build the JDK--this is called "bootstrapping".
There was some traffic on this list a few days ago about doing exactly the
same thing, and some of the discussion there suggested using IcedTea to do
the build, since (apparently)
It would be possible, but rather than writing CPU-specific compiler
ports the idea is to use something like libjit to add a generic one.
Cheers,

That's good progress, being able to build itself. I should take a look
at it. It's still going to be interpreter-only (without porting),
right? Would it still be possible to add a compiler port (c1, opto) on
top of it?
Thanks,

Hi Jonathan,
IcedTea (icedtea6 anyhow) has the zero-assembler port which should
build out of the box on any linux/gcc platform. I say should, because
it's new and we're still working out kinks, but it works enought to
build itself on 32- and 64-bit PowerPC, I've had reports of it working
on zSeri
Beyond just getting it to build, to Hotspot uses a fair amount of
machine code internally, which would have to be retargeted to the SuperH
ISA to get it to run. IcedTea helps, but my understanding is that there
would still be probably a few months of work required to support a new CPU.

Hi Olivier,
OpenJDK does indeed require java to build, but that aside there
is the issue that HotSpot does not support the sh4 processor.
Check out IcedTea instead (http://icedtea.classpath.org/) which
has a) the ability to bootstrap with gcj, and b) support for
building on platforms with no HotSp
