Jikes is unmaintained, and has been effectively dormant since 2005, at
least. It lacks support for generics, and annotations would likely be an
interesting problem, too. De-annotating & de-generifying the OpenJDK
class library too would be a lot of work of unlikely benefit, since the
tools themselves, like Javac, use Java 1.5 features.

You should be better off taking IcePick from
http://icedtea.classpath.org/wiki/IcePick and bootstrapping using that
on an existing JVM, assuming there is one for Haiku.
If there is no JVM for Haiku that can run ecj and IcePick, you could
consider starting the bootstrapping effort by first porting GNU
Classpath & Kaffe, Cacao, JamVM, etc.
to Haiku, to get a bootstrap VM for running ecj, and then going forward
with IcePick.

Alternatively, you should consider using a JVM on Linux for
bootstrapping purposes, as discussed in
http://landonf.bikemonkey.org/code/java/Porting_To_FreeBSD_Sparc.20080204.html
.
