Iterative development of a particular module, AWT for example (avoid having to build whole JDK)
export JDK7_BASE=/Volumes/Data/src/JDK7/macosx-port export JDK7_BUILD=$JDK7_BASE/build export ALT_BOOTDIR=$JDK7_BUILD/macosx-universal/j2sdk-image/ export ALT_JDK_IMPORT_PATH=$JDK7_BUILD/macosx-universal/j2sdk-image/ export ALT_OUTPUTDIR=$JDK7_BUILD/macosx-universal cd $JDK7_BASE/jdk/make/sun/awt/ make |
Settting bootclasspath, DYLD_LIBRARY_PATH and debugging with your changes:
compilation export _JAVA_OPTIONS=-Xbootclasspath/p:$JDK7_BUILD/macosx-universal/classes/ export DYLD_LIBRARY_PATH=$JDK7_BUILD/macosx-universal/lib/ $JAVA_HOME/bin/java -jar /Developer/Extras/Java/JFC/SwingSet2/SwingSet2.jar |
Download jtreg to run the tests in the /jdk/test directory.
File them at java.net/jira/browse/MACOSX_PORT.
