I talked to a lot of people about this today. What we really want is to not run tests when we build. Mikael and I were looking into how we could do that without gamma and there is a way:

http://cr.openjdk.java.net/~twisti/8006965/

This would be the first of three fixes:

Fix 1) The patch above removes test_gamma and uses some weirdness in the VM (-Dsun.java.launcher=gamma) to run it with an existing JDK; add test_{product,fastdebug,debug} targets

Fix 2) Remove gamma and all the ugly code that comes with it (copies of the jdk launcher in hotspot and other pieces); make the hotspot script work like the test targets in Fix 1

Fix 3) Remove the -Dsun.java.launcher=gamma and possibly replace the existing -Dsun.boot.library.path weirdness by explicit command line options like -Xbootlibrarypath:{/p,/a}

I'm not sure what the correct solution is, but when you do find out, the jdkpath.sh target should also be updated. How many are actually using the hotspot script? Would people be very sentimental if we would remove the gamma launcher altogether? Taking to people here it seems that most are copying their libjvm into a JDK and use java anyway. -- Chris

8006965: testgamma should run with import JDK Reviewed-by: Right now testgamma runs with the boot JDK which is JDK n-1 (where JDK n is the version we are actually compiling for). This setup is unsupported and thus should not be done during HotSpot builds. The fix is to always use JDKIMPORTPATH instead of JAVAHOME when running testgamma. make/bsd/makefiles/buildtree.make make/defs.make make/linux/makefiles/buildtree.make make/solaris/makefiles/buildtree.make
