Build issue : missing classanalyzer?

[Jing LV]

Hello,

I am trying to build jigsaw with openjdk7 (I am working on win2008
64bit). Download the source and overcome some configuration problems can
the build work till I see these these messages:

D:/cygwin/home/jdk7/build/windows-amd64/bin/java -XX:-PrintVMOptions
-XX:+UnlockDiagnosticVMOptions -XX:-LogVMOutput -Xmx512m -Xms512m -XX:PermSi
ze=32m -XX:MaxPermSize=160m \
-cp D:/cygwin/home/jdk7/build/windows-amd64/btjars/classanalyzer.jar \
com.sun.classanalyzer.Modularizer \
-jdkhome D:/cygwin/home/jdk7/build/windows-amd64 \
-update \
-classlistdir D:/cygwin/home/jdk7/build/windows-amd64/moduleinfo/classlist \
-modulepath D:/cygwin/home/jdk7/build/windows-amd64/modules
Error: Could not find or load main class com.sun.classanalyzer.Modularizer
make[3]: ***
[D:/cygwin/home/jdk7/build/windows-amd64/btjars/classanalyzer.jar] Error 1

Checking the directory and find no classanalyzer.jar. I find
classanalyzer(JSR308?) was not in the JDK7. Anyway I see this
classanalyzer may used in jigsaw project which I am studying, I am not
willing to omit it to pass the build. Can someone tell me how can I do
to build classanalyzer, or where to download a workable jar? Thanks a lot.
