-Xscdmx option to control the size of the class debug area when you create a shared classes cache.
See Using -X command-line options for more information about the
-Xscdmx option works in a similar way to the
-Xscmx option, which is used to control the overall size of the shared classes cache. The size of
-Xscdmx must be smaller than the size of
-Xscmx. By default, the size of the class debug area is a percentage of the free class data bytes in a newly created or empty cache.
A class debug area is still created if you use the
-Xnolinenumbers option with the
-Xscdmx option on the command line.
