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 -verbose:class 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 .../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.NetBeans/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,+
−
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/j2sdk1.5.0+
−
resultsdir=classlist-run+
−
iterations=1+
−
benchmarks=startup3+
−
