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

* GitHub does not return SSH authorization on a single line as Gerrit
does - need to account for that.

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.

Currently, SmartServiceInfoRefs always prints "# service=serviceName"
followed by a flush packet in response to an info/refs request, and then
hands it off to the specific service class. Printing of "#
service=serviceName" is mandated for protocol v0, but not v2.
Therefore, the existing code works for protocol v0, but whenever a
service that supports protocol v2 receives an info/refs request, it must
first determine which protocol version is to be used (depending on, for
example, the request and any relevant configuration variables), and then
decide if "# service=serviceName" needs to be printed.
Create a new method that v2-supporting service classes can override,
covering the printing of both "# service=serviceName" and everything
that the #advertise method prints. This will be used in a subsequent
commit in which UploadPackServlet (and the other classes it uses) is
updated to support protocol v2.
