BluRay discs with HDMV menus should work quite well (no BD-J required).

You don't want to build 0.2.3 with BD-J support (it won't play any BD-J
discs). You could try git snapshot from git.videolan.org.

With 0.2.3:

./configure --help
  [...]
  --with-jdk=DIR          Specify the path to the JDK (default is
                          "/usr/lib/jvm/java-6-openjdk")

With recent git snapshots:

./configure --help
  [...]
  Some influential environment variables:
    JDK_HOME    Path to the JDK [default=/usr/lib/jvm/java-6-openjdk]


Some OSX specific changes to configure.ac may be required. By default it
uses "-I${JDK_HOME}/include -I${JDK_HOME}/include/$java_os" as include
path. Probably also location of JVM library needs to be fixed.

Yes and no.
HDMV menus should work quite well without BD-J.
Support for BD-J menus in libbluray is not yet complete (all BD-J discs
won't play). Also some BD-J specific changes to vlc may be required.
