PropertyFile:
1. declare your string constant as final
2. don't declare token(StringTokenizer) as a private member, since it's not quite relevent to your class, declare it in the block where you are using it.
3. userSectionLeftMark = (leftMark==null)?defaultSectionLeftMark:leftMark;
and similar to the rest.
4. This block:
try{
      raf = new RandomAccessFile(path_and_name,mod);
      }catch(IllegalArgumentException arg){}
      catch(FileNotFoundException fileNotFound){}
I just don't feel right about this. It shouldn't be in the constructor because it's hard to deal with the exceptions(The general rule is to make your constructor as simple as possible). These exceptions are serious exceptions and it would be better to handle them, rather than leave them blank. This block shows at least 3 times in the file, so make a method of this.
5. The getValue(...) method: fix those String constants(the logic between user settings and default is twisted!), and move those checking out to somewhere else.
6. Whenever possible, catch all exceptions.
7. put your manaty.ini testing file in the comment too so users could follow you. Some of the comments are hard to understand.

My personal view for reference.
