The jdk/test/Makefile should be in both jdk7/tl and jdk6/jdk6 repositories now.
The jtreg tool is needed, so to download and install the latest jtreg tool do the following: wget http://www.java.net/download/openjdk/jtreg/promoted/b03/jtreg-4_0-bin-b03-31_mar_2009.zip unzip jtreg-4_0-bin-b03-31_mar_2009.zip export JT_HOME=`pwd`/jtreg Build your jdk image, e.g. cd jdk/make && gnumake all images Then run all the stable jdk tests: cd jdk/test && gnumake -k jdk_all If you have a 2 CPU machine and are feeling brave, try: cd jdk/test && gnumake -k -j 4 jdk_all If you do try this out, please let me know how it went. I'm still refining what tests are considered "stable" and I haven't completed my testing of Windows&CYGWIN, so I know the set of tests run will be changing a little. -kto
