Cleanup Exception handling

[jmax01]

• Removed calls to printStackTrace()` and replace with proper logging calls.
• Remove throws declarations if method doesn't throw the declared exceptions
• Do not swallow exceptions without logging the stack trace and adding comment as to why the exception is being swallowed
• Chain all exceptions
• Do not explicitly throw Throwable, Exception, or RuntimeException
• For phase 1 all new Throwable calls will be replaced with the following:
  • IllegalArgumentException Thrown when parameters are invalid. Message should contain the invalid parameter and, if possible, a message about valid values. If a non-nullable parameter is null an NPE may be thrown instead.
  • IllegalStateException Thrown when a value of an instance field is not valid for successful execution of a method.
