Community Process

I'd like to thank everyone who has downloaded, tested, and reported bugs. The result is "Developer Preview Release 2" -- Thanks!

If you haven't already, consider downloading a copy and running your software. Let me know how it works out for you!

Changes since Release 1

Features

• Support for 32-bit Mac OS X 10.4 Tiger.
• SoyLatte binary release.

Bug fixes

• Fix handling of setrlimit(RLIMIT_NOFILE, ...RLIM_INFINITY) on Leopard. Ensures that Java is able to raise the process file limit to the maximum allowed. (Reported by Tore Halset).
• Added official cacerts store from the BSD port, fixing SSL's x509 certificate validation (Reported by Tore Halset)
• Corrected the dylib path for loading the debugger library. Fixes java debugger (Fix suggested by Curtis Stanford, issue reported by Alexander Babaev)
• Add a missing LDFLAGS setting to the Darwin build configuration. Now correctly links JDK binaries, removing the requirement for setting DYLD_LIBRARY_PATH (Reported by Fred Jean and Nick Shanny)
• Key Leopard-specific uc_mcontext defines to MAC_OS_X_VERSION_MAX_ALLOWED >= 10.5. Fixes 64-bit builds on Tiger. (Reported by Ed Carrel).
• Added support for building against the 10.4 (and other) SDK using the DARWIN_SDK build setting
• Use DYLD_FALLBACK_LIBRARY_PATH for Java library loading. Avoids conflicts between Java libraries, and libraries enclosed in system frameworks. Fixes java2d binding against libGL.dylib

Fetching and Building from Source

Building

The build has been simplified. To build the 32-bit JVM:

cd control/make
make ALT_BOOTDIR=/System/Library/Frameworks/JavaVM.framework/Home \
ALT_MOTIF_DIR=/opt/local SYS_CFLAGS="" LANG="C" JAVA_HOME="" CLASSPATH="" \
LD_LIBRARY_PATH="" MAKEFLAGS="" SKIP_COMPARE_IMAGES="YES" \
BUILD_DEPLOY="false" ALT_DEVTOOLS_PATH=/usr ALT_CUPS_HEADERS_PATH=/usr/include \
HOTSPOT_BUILD_JOBS=1 PARALLEL_BUILD_JOBS=1

The following additional make options are available:

• BSD_OVERRIDE_ARCH: Set to amd64 to build the 64-bit JVM
• DARWIN_SDK: Set to target a specific Mac OS X SDK.

To build with extra debugging code and symbols, use the "debug_build" target.

To target Tiger, set the MACOSX_DEPLOYMENT_TARGET environmental variable to "10.4", and pass DARWIN_SDK=/Developer/SDKs/MacOSX10.4u.sdk as a make flag. The Tiger SDK currently must be build on Leopard, due to bugs in the 10.4 compiler's -mstackrealign code generation. This is on the long-term to-be-fixed list.

Fetching the source

Sources are available as a downloadable archive, or from a mercurial repository. To download the source code, you must be a licensee in good standing under the Java Research License. To ensure compliance, downloading the source requires authentication:

The development repository is also available via mercurial: http://hg.bikemonkey.org/javasrc_1_6_jrl_darwin/. The release tag is jdk6_devpreview_r2.

Please review the license at http://java.net/jrl.csp, and submit your license acceptance to Sun.

Binary Access

I am making available the SoyLatte binary release. (Red Hat already claimed IcedTea, and I drank a lot of double soy lattes while working on this. Plus, I think it's funny).

SoyLatte is based on the BSD Port of Sun's Java 6 JDK, and is made available under the Java Research License. JDK and Java are trademarks of Sun. Like RedHat, I want to make it exceptionally clear that while SoyLatte is a port of Java, it is not Sun's Java, JDK, or OpenJDK. Unlike IcedTea, SoyLatte is made available under the JRL. Please see below for a licensing discussion.

Downloads

Binaries are available for Mac OS X 10.4 and 10.5 (32-bit), and Mac OS X 10.5-only (64-bit). The soylatte directory can be placed anywhere on your system -- I chose /usr/local/soylatte16-amd64. Like other Java platforms, setting the JAVA_HOME and PATH environmental variables to point at these locations will work as expected.

Feature TODO List

I'll start looking at all of these eventually, but feel free to jump in:

• Sound support. If you know CoreAudio, your help is much appreciated!
• Integration with the Mac OS X certificate store (x509)
• Support for setting mach thread priority
• Native aqua Swing (as opposed to X11). This is a big one, and not likely to be done anytime soon. The effort needs to be led by someone familiar with Cocoa, JNI, and Swing

JSR 223 JavaScript Support

Sun has pulled Rhino from the JRL and OpenJDK (GPLv2) sources, due to concerns regarding licensing. As a work-around, there is a BSD-licensed javascript JSR223 engine implementation, using Rhino, available via https://scripting.dev.java.net/:

We have built and tested with Rhino version 1.6 release 5. There is a Rhino based JavaScript engine bundled in JDK 6 (http://jdk6.dev.java.net). The JDK 6 bundled version is based on Rhino 1.6 release 2. Unlike JDK 6 bundled engine, all Rhino features (optimizer, E4X) are enabled in this version.

This seems to work as a drop-in replacement for Sun's sun.org.mozilla code. Here's JavaScript Hello World using Rhino 1.6r5 and the Scripting package:

java -cp ~/Downloads/jsr223/javascript/build/js-engine.jar:/tmp/rhino1_6R7/js.jar:. EvalScript
Found engine factory: com.sun.phobos.script.javascript.RhinoScriptEngineFactory
Found engine factory: com.sun.phobos.script.javascript.EmbeddedRhinoScriptEngineFactory
Hello, World

I am looking into the feasibility of integrating this solution.

Licensing

The Mac OS X work is based heavily on the BSD Java port, which is licensed under the JRL. The BSDs develop Java under the JRL; FreeBSD has negotiated a license with Sun to distribute FreeBSD Java binaries based on the JRL sources.

As the Mac port stabilizes, I am merging my work upstream into the BSD port, and in turn, it is a goal of the FreeBSD Java project to merge their work into OpenJDK. I've signed a Sun Contributor Agreement in preparation for this, and an OpenJDK Porters group has been proposed: http://thread.gmane.org/gmane.comp.java.openjdk.general/630

While the JRL makes this initial port possible, OpenJDK's GPLv2+CE licensing makes development and distribution far simpler. I hope to contribute this work to OpenJDK as soon as is feasible.

Submitting Bug Reports

There are bugs, and you're likely to find one. The most useful bug report is one that includes a simple, compilable reproduction case -- that gives me what I need to track down the really tricky bugs.

In submitting a bug, please include the following information:

• An e-mail address I can use to contact you if I have any further questions
• If at all possible, a simple, compilable test case that reproduces the issue
• The java hotspot error log (hs_err_pid.log), if the JVM crashed.

Bug reports may be submitted to landonf (at) macports (dot) org.
