-This directory contains tools and tests associated with creating the
-class list for class data sharing.
-
-The class list is produced by running the refWorkload startup3 benchmark with
-the -XX:+TraceClassLoadingPreorder option.  The -Xshare:off option must also be
-used so that bootclasspath classes are loaded from rt.jar.  The MakeClasslist
-program should be built into the jar file makeclasslist.jar and is run
-on one of the logs from each of the benchmarks in the following fashion:
-
-cd .../<resultsdir>/results.startup3
-$JAVA_HOME/bin/java -jar makeclasslist.jar results.Noop/results_1/log results.Framer/results_1/log results.XFramer/results_1/log results.JEdit/results_1/log results.LimeWire/results_1/log results.NetBeans50/results_1/log
-
-Presently, $JAVA_HOME must be the same path used to run the startup3 benchmark.
-
-The logs are deliberately concatenated in roughly smallest to largest order
-based on application size.  The resulting output is redirected into a file
-and results in one of classlist.solaris, classlist.linux, classlist.macosx,
-or classlist.windows.  These files are checked in to the workspace.  A
-necessary checksum (AddJsum.java) is added to the final classlist
-(installed in lib/ or jre/lib/) during the build process by the
-makefiles in make/java/redist.
-
-In a forthcoming JDK build we plan to manually add the dependent
-classes for the calendar manager Glow, which pulls in the Preferences
-classes and, on Unix platforms, the XML parsing classes.
-
-The properties file supplied to the refworkload is approximately the
-following:
-
-javahome=/usr/java/j2sdk1.8.0
-resultsdir=classlist-run
-iterations=1
-benchmarks=startup3
-globalvmoptions=-client -Xshare:off -XX:+TraceClassLoadingPreorder
