-Xscdmx

Use the -Xscdmx option to control the size of the class debug area when creating a shared class cache.

-Xscdmx<size>

The -Xscdmx option works in a similar way to the -Xscmx option used to control the overall size of the shared class cache. The size of -Xscdmx must not exceed the size of -Xscmx. By default, the size of the class debug area is a percentage of the free bytes in a newly created or empty cache.

size is expressed as an absolute value.

A class debug area is still created if you use the -Xnolinenumbers option with the -Xscdmx option on the command line.
