Review comment:
       @nealrichardson Please check if the following notes are reasonable for Java. Thanks for your effort.
   
   The Java package has supported a number of new features. 
   Users can validate vectors in a wider range of aspects, if they are willing to take more time. 
   In dictionary encoding, dictionary indices can be expressed as unsinged integers.
   A framework for data compression has been setup for IPC.  
   
   The calculation for vector capacity has been simplified, so users should experience notable performance
   improvements for various 'setSafe' methods. 
   
   Bugs for JDBC adapters, sort algorithms, and ComplexCopier have been resolved to make them more usable.
