What you do is in your class have something like this:

HashtMap<String,Thing> map1;
HashMap<String,String> map2;

public Map getMap1() { return map1; }
public Map getMay2() { return map2; }

Or you don't expose the raw Maps, but just offer a few wrapper methods
that call methods on your two maps.

public boolean put1( String s, Thing t)
{
 return map1.put( s, t );
}

It should not be considered an error when the user starts something
already started or stops something already stopped. This applies
to browsers, services, editors... It is inexcusable to 
punish the user by requiring some elaborate sequence to atone,
e.g. open the task editor, find and kill some processes.
