Remove further unnecessary 'final' keywords

Remove further unnecessary 'final' keywords

Remove it from

 * package private functions.

 * try blocks

 * for loops

this was done with the following python script:

$ cat f.py
import sys
import re
import os

def replaceFinal(m):
  return m.group(1) + "(" +  m.group(2).replace('final ', '') + ")"

methodDecl = re.compile(r"^([\t ]*[a-zA-Z_ ]+)\(([^)]*)\)")

def subst(fn):
  input = open(fn)
  os.rename(fn, fn + "~")

  dest = open(fn, 'w')
  for l in input:
    l = methodDecl.sub(replaceFinal, l)
    dest.write(l)
  dest.close()

for root, dirs, files in os.walk(".", topdown=False):
  for f in files:
    if not f.endswith('.java'):
      continue

    full = os.path.join(root, f)
    print full
    subst(full)
