If I run
git config --global protocol.version 2
mkdir repo
cd repo
git init --bare
git remote add origin https://go.googlesource.com/proposal
git fetch --depth=1
git fetch --unshallow
then I expect to have a full history, just as though I had fetched
without --depth in the first place. Instead, it reports success
but does not fetch enough objects:
$ git fsck
notice: HEAD points to an unborn branch (master)
Checking object directories: 100% (256/256), done.
Checking objects: 100% (468/468), done.
broken link from commit 2c6bc83f234085c8eadb7ea33405ce6223c44d1b

dangling commit 314be00dae78dd526851f5635e6349014e2ad0c2
The false success indicates problems in the client and the server.
Git 2.18-rc2 (the client) ought to have been more defensive, noticing
the incomplete history. The greater error is in JGit (the server),
which neglects to send the objects requested.
When serving protocol v0 requests, JGit sends the correct objects by
taking unshallowCommits into account when generating the pack to send
to the client. Do the same in the protocol v2 code path. I forgot to
do this in v5.0.0.201806050710-rc3~6 (Teach UploadPack shallow fetch
in protocol v2, 2018-03-15).

Instead, do it when we return the first PlotCommit from next().
On a repository with many refs, getAllRefsByPeeledObjectId() can
take a while. Doing a late initialization simplifies the handling
of a PlotWalk.
EGit, for instance, creates and configures an instance, and then
does the real walk in a background job. With late initialization,
the potentially expensive getAllRefsByPeeledObjectId() also occurs
in that background job.

Eclipse platform uses this version from the Oxygen Orbit release for
Photon. In order to avoid that we end up with two slightly different
versions in the same p2 repository of the simultaneous release we
downgrade temporarily from the version 4.5.2.v20180410-1551 in the
Photon Orbit release.

JGit now considers lightweight tags only if the --tags option is set
i.e. `git.describe().setAllTags(true)` has to be set, else the default
is now as in c git:
Only annotated tags are evaluated unless you pass true
equivalent to --tags (or --all) by the option setAllTags.
Hint: This (still) doesn't address any difference between c-git
`--all` and `!--all --tags` behavior;
perhaps this might be a follow up request

Jsch checks only for the availability of the algorithms given by
Jsch-internal config keys "CheckCiphers", "CheckKexes", and
"CheckSignatures". If the ssh config defines any algorithms
unknown to Jsch not listed in those keys, it'll still propose them
during the negotiation phase, and run into an NPE later on if the
server happens to propose such an algorithm and it gets chosen.
Jsch reads those "CheckCiphers" and the other values from either a
session-local config, or the global static Jsch config. It bypasses
~/.ssh/config for these values.
Therefore, copy these values from the config as read from
~/.ssh/config into the session-specific config. That makes Jsch
check _all_ configured algorithms up front, discarding any for
which it has no implementation. Thus it proposes only algorithms
it actually can handle.

From the javadoc for Files.list:
"The returned stream encapsulates a DirectoryStream. If timely disposal
of file system resources is required, the try-with-resources construct
should be used to ensure that the stream's close method is invoked
after the stream operations are completed."
This is the only call to Files#newDirectoryStream that is not already in
a try-with-resources.

Zip Slip [1] is an arbitrary file write generic vulnerability, that can
be achieved using a specially crafted zip (or bzip2, gzip, tar, xz, war)
archive, that holds path traversal filenames.
According to Maven's announcement [2] several plugins use plexus-archiver to
unpack dependencies to disk and have been identified as potential triggers
for exposing the vulnerability.
Of those, JGit uses the maven-dependency-plugin and the maven-javadoc-plugin.
Update them to the fixed versions reported in [2].
See the corresponding issues for the maven-dependency-plugin [3] and the
maven-javadoc-plugin [4] for details.
