Currently, when running with a CDS archive and a class path mismatch is detected, the following error/warning will be logged:

shared class paths mismatch (hint: enable -Xlog:class+path=info to diagnose the failure)

However, the same error/warning is being logged even though the -Xlog:class_path=info is specified.

Suggestion: if the -Xlog:class+path=info is specified, the log message should just simply be:
shared class paths mismatch
