Applied parameters and squashed all compiler warnings.
Changed loops to enhanced for where appropriate.
Fixed SoftValueHashMap:
Made it a raw type.
Overwritten implementation of the `get` method correctly unwrapped the reference but the methods
`containsValue` and `entrySet` needed to be fixed.
Implemented the remaining outstanding methods from the `java.util.Map` contract `values`, `putAll`
and `keySet`.
Dropped `AbstractMap` inheritance as we were not inheriting anything anymore.
Changed internal map to `ConcurrentHashMap' to be atomic and parallel safe.
Found original unit tests from jboss retro which are now updated to reflect the javassist
versions of the scoped pool classes. Added tests for the SoftValueHashMap including
test which overloads the heap to ensure the cache cleans itself appropriately.
The following were applied during multiple itterations through the source.
* Parameterize raw types.
* Mark unused members.
* Annotate override and deprecated methods.
* Convert loops to enhance for loop.
* Remove redundant else statements.
* Widening collection type references.
* Optimize code for improved readability.
* Squash compiler warnings.
* Identify smells.
