> Prior to this patch, if `--module-path` is specified in the command line:
> during CDS dump time, full module graph will not be included in the CDS archive;
> during run time, full module graph will not be used.
> 
> With this patch, the full module graph will be included in the CDS archive with the `--module-path` option. During run time, if the same `--module-path` option is specified, the archived module graph will be used.
> 
> The checking of module paths between dump time and run time is more lenient compared with the checking of class paths; the ordering of the modules is unimportant, duplicate module names are ignored.
> E.g. the following is considered a match:
> dump time      runtime
> m1,m2             m2,m1
> m1,m2             m1,m2,m2
> 
> I included some [notes](https://bugs.openjdk.org/browse/JDK-8328313?focusedId=14699275&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14699275) in the bug report regarding some changes in the corelib classes.
