JDT Core's FileSystem.moduleUpdates field, we had to make it public
there first.

I am expecting the test case to pass, but other tests to fail. This
temporary commit is meant to create feedback from GitHub CI test runs.

The documentation specifies annotation style pointcuts
can use if(false) or if(true) and not require a boolean
return value and body for the @Pointcut annotated
method but it doesn't work without this change to validation
that recognizes the situation.

Fixes #115

StringBuffer is a legacy synchronized class. StringBuilder is a direct replacement to StringBuffer which generally have better performance.

It means that separate File.exists() check before File.isDirectory() check is redundant.

Change calls like
  pre.scope.parent = newParent;
to this pattern:
  // Use setter in order to also update member 'compilationUnitScope'
  pre.scope.setParent(newParent);

This should fix lots of failing tests after updating JDT Core.

I was debugging something in ModuleTests, trying to find out if there
are resource leaks. They were not in this class but in FileUtil - see
next commit. However, the little refactoring here does not hurt either.

Reports on declarations of Collection variables made by using the collection class as the type, rather than an appropriate interface.

Reports Collection.addAll() and Map.putAll() calls after instantiation of a collection using a constructor call without arguments. Such constructs can be replaced with a single call to a parametrized constructor which simplifies code. Also for some collections the replacement might be more performant.

There are two styles to convert a collection to an array: either using a pre-sized array (like c.toArray(new String[c.size()])) or using an empty array (like c.toArray(new String[0]).
In older Java versions using pre-sized array was recommended, as the reflection call which is necessary to create an array of proper size was quite slow. However since late updates of OpenJDK 6 this call was intrinsified, making the performance of the empty array version the same and sometimes even better, compared to the pre-sized version. Also passing pre-sized array is dangerous for a concurrent or synchronized collection as a data race is possible between the size and toArray call which may result in extra nulls at the end of the array, if the collection was concurrently shrunk during the operation.
