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.

Reports common usage patterns of java.util.Map that could be replaced with Java 8 methods: getOrDefault(), computeIfAbsent(), putIfAbsent(), merge(), or replaceAll().

Reports the copying of array contents to a collection where each element is added individually using a for loop. Such constructs may be replaced by a call to Collection.addAll(Arrays.asList()) or Collections.addAll().

Reports "unboxing", e.g. explicit unwrapping of wrapped primitive values. Unboxing is unnecessary under Java 5 and newer, and can be safely removed.

Reports explicit boxing, i.e. wrapping of primitive values in objects. Explicit manual boxing is unnecessary under Java 5 and newer, and can be safely removed.

The method implements finding a field object in the 'fieldsList' with a given name. If found, return the found field object, otherwise return null.
Thus, rename the method as "findsField" should be more clear than "containsField" since "containsField" is prone to ask whether the "fieldsFile" contains a field or not and return true or false.

This commit introduces some new methods into the
runtime Factory class and modifies code generation
to use them (and to use the form of the LDC bytecode
that loads class constants).

Multiple changes here:
- annotation unpacking is smarter and if it only needs runtime
retention annotations it uses reflection and doesn't unpack the
bytes to discover class level retention annotations.
- Reflection worlds are shared if for the same classloader.
