whenever possible... I agree

I do have given a try to
-I/System/Library/Frameworks/JavaVM.framework/Headers/
and it works...
a the condtion to change the linking instructions (see below).

Bingo !
the optional.jar was missing !
Now using the ant shipping with JBuilderX (1.5.4)

so the C/pljava/Makefile is now

#-----------------------------------------------------------------------

#
# Makefile--
# Makefile for pljava
#
#-----------------------------------------------------------------------

NAME := pljava

include $(MODULEROOT)/Makefile.global

ifeq ($(PORTNAME), win32)
DLL_BUILD := 1
else
ifeq ($(PORTNAME), cygwin)
DLL_BUILD := 1
override CPPFLAGS := -DCYGWIN $(CPPFLAGS)
else
ifeq ($(PORTNAME), darwin)
override CPPFLAGS :=
-I/System/Library/Frameworks/JavaVM.framework/Headers/ $(CPPFLAGS)
else
JRE_INCL := $(PORTNAME)
ifeq ($(host_cpu), i686)
JRE_LIB := lib/i386/client
else
JRE_LIB := lib/$(host_cpu)/client
endif
endif
endif
endif

ifdef DLL_BUILD
JRE_INCL := win32
JRE_LIB := bin/client

# This works but is not very nice since it affects all
# DLLTOOL invocations in Makefile.shlib. A custom flag
# is requested from postgres.
#
override DLLTOOL := $(DLLTOOL) --add-stdcall-alias
endif

ifdef USE_GCJ
override CPPFLAGS := -DGCJ $(CPPFLAGS)
SHLIB_LINK = $(BE_DLLLIBS) -lgcj -lwsock32
else
ifeq ($(PORTNAME), darwin)
SHLIB_LINK = $(BE_DLLLIBS) -L. -framework JavaVM
else
override CPPFLAGS := -I$(JDK_HOME)/include
-I$(JDK_HOME)/include/$(JRE_INCL) $(CPPFLAGS)
SHLIB_LINK = $(BE_DLLLIBS) -L. -L$(JDK_HOME)/jre/$(JRE_LIB)
-ljvm
endif
endif

... no changes after that

The change
#ifdef DARWIN
#include <JavaVM/jni.h>
#else
#include <jni.h>
#endif
shoudl not be necessary anymore.

Now everything compiles,
regarding the tests : do you have any more precise instructions to
follow than what is in the README ?
