Use Map interface instead of ConcurrentHashMap class
On Android, the co-variant override of ConcurrentHashMap.keySet()
introduced in Java 8 was undone. [1] If compiled Java code calls that
co-variant override directly, one gets a NoSuchMethodError exception
at run-time on Android.
Making the code call that method via Map.keySet() side-steps this
problem.
This is similar to bug 496262, where the same problem cropped up when
compiling with Java 8 against a Java 7 target, but here we cannot use
bootclasspath. We build against Java 8, not against the Android version
of it.
Recent Android versions should have some bytecode "magic" that adds the
co-variant override in bytecode (see the commit referenced in [1]), but
on older Android version this problem may still occur. (Or perhaps the
"magic" is ineffective...) There are two pull requests on Github for
this problem, both from 2020, [2][3] while the Android commit [1] is
from March 2018. Apparently people still occasionally run into this
problem in the wild.

If a file exists in head, merge, and the working tree, but not in
the index, and we're doing a force checkout, the checkout must be
an "update", not a "keep".
This is a follow-up on If3a9b9e60064459d187c7db04eb4471a72c6cece.

Do not export the test-only package org.eclipse.jgit.transport from
bundle org.eclipse.jgit.ssh.jsch.test. Doing so can confuse the build
in Eclipse: other bundles that import this package may then also pick
up this test package, leading to non-test sources depending on test
sources and to build cycles.

Split out loose object handling from ObjectDirectory
The ObjectDirectory class manages the interactions for the entire object
database, this includes loose objects, packfiles, alternates, and
shallow commits. To help reduce the complexity of this class, abstract
some of the loose object specific details into a class which understands
just this, leaving the ObjectDirectory to focus more on the interactions
between the different mechanisms.
