Note that only Mac OS X 10.7 will be an Oracle-supported platform. It should continue to run on 10.6.8 + Java for Mac OS X 10.6 Update 6 but that is not guaranteed. As of 1-Jan-2012 there are no plans to introduce 10.7-only APIs into the codebase.

If you install Xcode after installing the Apple provided Java for Mac OS X, you will have to re-install the same Java for Mac OS X or a later developer preview to correct headers in the JavaRuntimeSupport framework. This issue is expected to be resolved in a future release of Xcode. As of Xcode version 4.3 you have to manually install the Command Line Tools. This package is no more included by default. (Start Xcode, open preferences, open tab Downloads and there install the missing component.) |

If you have the Java Developer Package installed:
$JAVA_HOME/bin/java -jar /Library/Java/Demos/JFC/SwingSet2/SwingSet2.jar |
On Mac OS X 10.6 use the alternate location for the SwingSet2.jar:
$JAVA_HOME/bin/java -jar /Developer/Extras/Java/JFC/SwingSet2/SwingSet2.jar |
Download jtreg to run the tests in the /jdk/test directory.
