   The primary aim of this PR is to trim off the white spaces. I can give you 
an example here.

   For large JSP files these white spaces are tremendous and also useless when 
passed over the network. The white spaces are good for readability for the 
user, and are not necessarily needed as source-compiled files. 
   Removing these white spaces result in fewer writes to internal buffers and 
fewer flushes to the network and thus results in lower latency.
