Changes to Apache Commons Lang:

• Removed reflective equals and hashCode. You generally use equals and hashCode for hash based collections, reflection has no place there.
• Removed initialOddNumber and multiplierOddNumber from HashCodeBuilder. We have never seen anybody use anything else than the default.
• EqualsBuilder#append(Object, Object) and HashCodeBuilder#append(Object) are simpler due to removed support for arrays.
  • If you want array support use EqualsBuilder#appendDeep(Object, Object) or HashCodeBuilder#appendDeep(Object). Is this the same pattern that java.util.Objects and java.util.Arrays use.
• Delegate to java.util.Objects, java.util.Arrays, java.lang.Long, java.lang.Double where possible.
  • This may benefit from future optimizations.
• More JDK compliant hashing:
  • use 31 instead of 37 as a hash code multiplier
  • use JDK hash code for booleans
