Sorry, I assumed that was what we always used, but since you are surprised that means we need to discuss it :-)

I've learned this style from Hibernate code reading, but I could be wrong or have read the wrong examples; the rule I learned - and I think if you look at the majority of code that matches - we always use a space separator with the exceptions of:
- constructor invocations
- catch clauses

but let's find an agreement on the mailing list.
