Description

IvyBuildNumber.java -> doExecute()

creates an inline patternMatcher with this method:

IvyBuildNumber.java

public Matcher getMatcher(String expression) {
                if ((expression == organisation)
                        || (expression == module)
                        || (expression == branch)) {
                    return exact.getMatcher(expression);
                }
                return regexp.getMatcher(expression);
            }

I'm guessing the == comparison is a typo ? Shouldn't it be saying .equals ?
I've been having issues with this task - non-deterministic results - I got down in my debug to this place where I get wrong matcher when
reference address comparison fails.
