# Modularizing the JDK

# - Post jdk build process until the source tree is restructured

#   for modules build

# - <outputdir>/modules/<module> will be created for each module.

#

# Steps:

# 0. During jdk build before this makefile is invoked, classes, 

#    resource files, and other non-class files such as native libraries,

#    properties file, images, etc are created.

#

#    Non-class files are copied to <outputdir>/tmp/modules/<MODULE>

#    directory in this step to prepare for the post-build modularization. 

#

#    The MODULE variable defined in other makefiles specifies 

#    the lowest-level module that the non-class files belong to.

#    The name might or might not be the same as the name of the modules 

#    in the resulting <outputdir>/modules directory.

#    

# 1. Unpack all jars in the <builddir>/lib directory to a temporary 

#    location (<outputdir>/tmp/modules/classes) to prepare for modules

#    creation.

#

# 2. Run ClassAnalyzer tool to analyze all jdk classes and generate

#    class list for all modules and also perform dependency analysis. 

#

#    Input configuration files :-

#

#    modules.config : defines the low-level modules and specifies 

#       what classes and resource files each module includes.

#    modules.group  : defines the module groups and its members.

#    jdk7.depconfig : lists the dynamic dependencies including

#       use of reflection Class.forName and JNI FindClass and

#       service provider.

#    optional.depconfig : lists the optional dependencies

#

# 3. Create one directory for each module (<outputdir>/modules/<module>)

#    based on the output files from (2).

#       

#    modules.list lists the modules to be created for the modules

#    build and its members. For each module (m) in modules.list,

#    a. create $m/lib/$m.jar with all classes and resource files

#       listed in $m.classlist and $m.resources respectively.

#    b. copy all non-class files from its members to 

#       <outputdir>/modules/$m.
