Replace "size() > 0" with "!isEmpty()" where appropriate.

In the Status implementation we can drop the check; the subsequent
loop will only execute when the list is non-empty anyway.

This avoids we show a stacktrace on the console by default when this
type of exception is thrown during the run method is executed.

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)

The multiValued attribute on @Option was removed. When the field is a
List, it's not actually needed (even with earlier versions of args4j),
see RmTest. In other cases, we have a custom handler, where it's also
not needed.

Since the introduction of generic type parameter inference in Java 7,
it's not necessary to explicitly specify the type of generic parameters.

Enable the warning in Eclipse, and fix all occurrences.

The underlying problem is that System.out is a PrintWriter and
as such it does not throw exceptions on error, but rather just
sets a flag and continues.

This changes replaces the use of System.out with a PrintWriter-like
writer that does not catch error, but instead throw them to the
caller.

Its confusing that a new TreeWalk() needs to have reset() invoked
on it before addTree().  This is a historical accident caused by
how TreeWalk was abused within ObjectWalk.

Drop the initial empty tree from the TreeWalk and thus remove a
number of pointless reset() operations from unit tests and some of
the internal JGit code.

Existing application code which is still calling reset() will simply
be incurring a few unnecessary field assignments, but they should
consider cleaning up their code in the future.

The strings are externalized into the root resource bundles.
The resource bundles are stored under the new "resources" source
folder to get proper maven build.

Strings from tests are, in general, not externalized. Only in
cases where it was necessary to make the test pass the strings
were externalized. This was typically necessary in cases where
e.getMessage() was used in assert and the exception message was
slightly changed due to reuse of the externalized strings.
