I have the following regular expression: ([0-9]+),'(.)':([0-9]+),(L|R|'.') It matches this just fine: 1,'a':1,R However, if I replace a with a space, it fails: 1,' ':1,R Why doesn't . match it? Is a space not classified as a character? I can't use \s because I don't want to match tabs and line breaks. I also tried: ([0-9]+),'(....

Is this an instance where I would use a mutex? Should I use a Queue.Synchronized instead and fill it up with all 300,000 ID's or is this ...
