Description

If you have JavaScript code like the following:

var x = 1;
var y = "" + ++x;

It is a legal operation. However, if this code is run through the maven-javascript-plugin, the second line becomes something like this:

var y=""+++x;

This yields an invalid increment operand. Instead, the space between the "" and the "+" must be preserved. I also suspect (but have not tested) this may be a problem with this code too:

var a = 1;
var b = a++ + "";

I suspect the increment and the decrement tokens in the obfuscater just need to be tagged as space sensitive (both before and after)--so we don't remove the spaces when compacting the code.
