commit 6996806101b69a87ffcfc4fa9237c075105d722f
Author: Richard Eckart de Castilho <r...@apache.org>
AuthorDate: Sat Aug 15 05:25:54 2020 +0200

    [LANG-1596] ArrayUtils.toPrimitive(Object) does not support boolean and 
other types (#607)
    
    - Add support for the missing types to toPrimitive(Object)
    - Added tests for toPrimitive methods which did not have test coverage yet
    - Added explicit test for the toPrimitive(Object) method for all primitive 
types
