Use constants from StandardCharsets instead of hard-coded strings
Instead of hard-coding the charset strings "US-ASCII", "UTF-8", and
"ISO-8859-1", use the corresponding constants from StandardCharsets.
UnsupportedEncodingException is not thrown when the StandardCharset
constants are used, so remove the now redundant handling.
Because the encoding names are no longer hard-coded strings, also
remove redundant $NON-NLS warning suppressions.
Also replace existing usages of the constants with static imports.

So far, in order to get the pack directory it was necessary to resolve
it from the object directory. This resolution is already done when
creating the object directory, so simplify the call by just adding a
getter to the pack directory.

check for an individual object.
The read-only FsckPackParser which will parse all objects within a pack

Run with @Parameterized, so we don't have to duplicate test setup for
each atomic/non-atomic test. We still have to have two different sets of
asserts for the cases where the behavior is different. In fact, this is
a readability win: it emphasizes that performing the exact same setup
except for the atomic setting will have different behavior.

When running an automatic GC on a FileRepository, when the caller
passes a NullProgressMonitor, run the GC in a background thread. Use a
thread pool of size 1 to limit the number of background threads spawned
for background gc in the same application. In the next minor release we
can make the thread pool configurable.
In some cases, the auto GC limit is lower than the true number of
unreachable loose objects, so auto GC will run after every (e.g) fetch
operation. This leads to the appearance of poor fetch performance.
Since these GCs will never make progress (until either the objects
become referenced, or the two week timeout expires), blocking on them
simply reduces throughput.
In the event that an auto GC would make progress, it's still OK if it
runs in the background. The progress will still happen.
This matches the behavior of regular git.
Git (and now jgit) uses the lock file for gc.log to prevent simultaneous
runs of background gc. Further, it writes errors to gc.log, and won't
run background gc if that file is present and recent. If gc.log is too
old (according to the config gc.logexpiry), it will be ignored.

Define MonotonicClock interface for advanced timestamps
MonotonicClock can be implemented to provide more certainity about
time than the standard System.currentTimeMillis() can provide. This
can be used by classes such as PersonIdent and Ketch to rely on
more certainity about time moving in a strictly ascending order.
Gerrit Code Review can also leverage this interface through its
embedding of JGit and use MonotonicClock and ProposedTimestamp to
provide stronger assurance that NoteDb time is moving forward.

Java 8 fixed the silent flush during close issue by
FilterOutputStream (base class of BufferedOutputStream)
using try-with-resources to close the stream, getting a
behavior matching what JGit's SafeBufferedOutputStream
was doing:
try {
flush();
} finally {
out.close();
}
With Java 8 as the minimum required version to run JGit
it is no longer necessary to override close() or have
this class. Deprecate the class, and use the JRE's version
of close.

A JUnit TestRule which enables to run the same JUnit test repeatedly.
This may help to identify the root cause why a flaky tests which succeed
most often does fail sometimes.
Add the RepeatRule to the test class containing the test to be repeated:
public class MyTest {
@Rule
public RepeatRule repeatRule = new RepeatRule();
...
}
and annotate the test to be repeated with the @Repeat(n=<repetitions>)
annotation:
@Test
@Repeat(n = 100)
public void test() {
...
}
then this test will be repeated 100 times. If any test execution fails
test repetition will be stopped.

Move `RepositoryTestCase.indexState` to parent class
The test helper method `indexState` in `RepositoryTestCase` is
very useful for writing tests, even in cases where we need to
do things like create more than one repository for a test and
thus we don't want to use the built-in `db` member variable that
exists in `RepositoryTestCase`. Since the method is static,
we can move it up to the parent class `LocalDiskRepositoryTestCase`,
where it can be used by tests that aren't a great fit for inheriting
directly from `RepositoryTestCase`.

Use local variable in RepositoryTestCase.indexState
There is a signature of the test helper method `indexState`,
in `RepositoryTestCase`, that accepts a `Repository` object
as an argument. However, there was one line of code where
this variable was not being used, and the method was instead
referring to a member variable `db`. I believe this was
probably just an oversight in a previous refactor, and
that the correct behavior is to use the variable from
the argument list. This change also has the benefit
of making it possible to convert this method to a static
method, since it no longer relies on any state from the class.

CherryPickCommand only works on a non-bare repository, as it must
modify the working tree and index in case of a merge conflict. In
tests, being able to recover from a merge conflict is less important,
as the caller should be able to control the full contents of files in
advance of the cherry-pick.
