    27  * This tool is used to help create the class list for class data sharing.

    28  *

    29  * The classlist is produced internally by first running a select number of

    30  * startup benchmarks with the -XX:DumpLoadedClassList=<file> option, then

    31  * running this tool in the following fashion to produce a complete classlist:

    32  *

    33  * jjs -scripting makeClasslist.js -- list1 list2 list3 > classlist.platform

    34  *

    35  * The lists should be listed in roughly smallest to largest order based on

    36  * application size.

    37  *

    38  * After generating the classlist it's necessary to add a checksum (using

    39  * AddJsum.java) before checking it into the workspace as the corresponding

    40  * platform-specific classlist, such as make/data/classlist/classlist.linux
