Unfortunately, while a short option with an argument works, the other forms
don't.  Using the test program below, I get the following:

java ArgTest -T -a
[before parsing]
[after parsing]
[[Option , [null] ], [Option , [a] ]]

java ArgTest --trace -a
[before parsing]
[after parsing]
[]

java ArgTest --trace=foo -a
[before parsing]
[after parsing]
[]

import org.apache.avalon.excalibur.cli.*;

class ArgTest {
    private static final int                ALL_OPT           = 'a';
    private static final int                TAINT_OPT         = 'T';
 
    protected final static CLOptionDescriptor TAINT           =
        new CLOptionDescriptor( "taint",
                                CLOptionDescriptor.ARGUMENT_OPTIONAL,
                                TAINT_OPT,
                                "turn on tainting checks (optional level)." );
 
    protected final static CLOptionDescriptor ALL             =
        new CLOptionDescriptor( "all",
                                CLOptionDescriptor.ARGUMENT_DISALLOWED,
                                ALL_OPT,
                                "all");
 
 
    public static void main(String[] args) {
        final CLOptionDescriptor[] options = new CLOptionDescriptor[]
        {
            ALL, TAINT
        };
 
        System.out.println("[before parsing]");
 
        final CLArgsParser parser = new CLArgsParser( args, options );
 
        System.out.println("[after parsing]");
 
        System.out.println(parser.getArguments());
    }
}
