A DESCRIPTION OF THE REQUEST :
The "javac" tool allows the use of:

@<filename> to "Read options and filenames from file"

Please provide the same functionality for the "java" tool.

JUSTIFICATION :
Very often, the compile and runtime classpath are identical. Adding this functionality will allow both command-lines to share the same configuration.

Currently we need to manually sync the data between the external file for javac and inline value for java.
