I was encountering SIGSEGVs using the scsl-j{re,dk}15 packages due
to a call to inflate_fast.  Turns out that this problem arises as
the JDK bundles an older version of zlib as libzip.so, but neglects
to conceal all the zlib's exported symbols, which causes a conflict
when using any other libraries linking to the system's libz.so (Sun
bug #4953050).  After lots of digging, it turns out the only way
to rectify this is to rebuild from source, and cause the build to use
the system's zlib.  So I did.

While I was at it, I also looked into what would be necessary to
get the Mozilla/Firefox plugin to work.  It turns out to be
surprisingly simple.

I've attached patches that, on top of Todd's and the BSD Java
patchset 4, will build the JDK and Mozilla/Firefox plugin.  If you
want to build it yourself, here are the steps:

 1. Fetch both the JDK Sources (jdk-1_5_0-src-scsl.zip) and Binaries
    (jdk-1_5_0-bin-scsl.zip) from Sun 
    <http://www.sun.com/software/communitysource/j2se/java2/download.xml>

 2. Fetch the FreeBSD JDK patchset #4 from 

	http://www.eyesbeyond.com/freebsddom/java/jdk15.html

 3. Fetch Todd's patches from <http://www.duh.org/NetBSD/java2/>
    (labelled `Local-patch-duh1').

 4. Unzip the jdk-1_5_0-src-scsl.zip and jdk-1_5_0-bin-scsl.zip in
    a directory somewhere (referenced as JDKDIR).

 5. Untar the FreeBSD JDK patchset #4; the actual patchfile is
    called jdk15.patches.  Run the following from your JDKDIR:

	patch -p0 < .../jdk15.patches

    This should apply cleanly (`echo $?' should be 0)

 6. Apply Todd's patches in a similar fashion:

	zcat duh-jdk15-patches-1.bz2 | patch -N -p0

    This patchset will not apply cleanly.  The first patch, to
    awt_motif21.c, was incorporated into the FreeBSD JDK patchset #4.
    The last patch to the ns7-adapter/Makefile will have its second
    chunk fail: one of the patches appended below fix this.

 7. Apply the patches below.

 8. Return to the JDKDIR, and run the following (with suitable
    replacements for your JDK, browser):

	unset LANG
	unset JAVA_HOME
	unset CLASSPATH
	unset LD_LIBRARY_PATH
	export ALT_MOTIF_DIR=/usr/pkg
	export ALT_MOZILLA_HEADERS_PATH=/usr/pkg/include/firefox2
	export ALT_BOOTDIR=/usr/pkg/java/sun-1.5/
	export BROWSER=firefox
	export HOTSPOT_BUILD_JOBS=3
	export ALT_CACERTS_FILE=/usr/pkg/java/sun-1.5/lib/security/cacerts

	# these are optional
	export SKIP_COMPARE_IMAGES=YES
	export DONT_ENABLE_IPV6=YES

	cd control/make && gmake || exit

    Assuming it all works, you should find the result in 
    control/build/<platform> (my platform was bsd-i586). There
    are three directories of interest: j2sdk-image, j2re-image,
    and j2sdk-debug-image.  You should be able to do something
    like:

	$ cd control/build/<platform>/j2sdk-image/demo/jfc/Java2D
	$ ../../../bin/java -jar Java2Demo.jar"

    Assuming that runs, copy the j2sdk-image directory somewhere.
    Put a symbolic link to jre/plugin/i386/ns7/libjavaplugin_oji.so 
    in your /usr/pkg/lib/firefox2/plugin/ directory, restart your
    browser, and you should be set.

Thanks to Todd for packaging the native Sun JDK together in the
first place, and to the groups who did all the hard work in porting
the JDK to BSD!

Brian.
