The (moxie and other) Launcher do not work with Java 9 and later anymore.
It used to dynamically extend the classpath, misusing an internal
interface of the `URLClassLoader`. This is no longer possible since Java 9,
which closed that path and does not offer any way to dynamically extend
the classpath during runtime.
So the choice is between providing one large Jar with everything in it,
providing a Jar that has the Jars in `ext` listed explicitly in its
manifest, and specifying the classpath on the command line where
the `ext` directory can be added and all contained jar files will
be put on the classpath.
The motivation for the Launcher class was to be able to simply drop
new jar files into a directory and they will be picked up at the
application start, without having to specify a classpath. We opt
for solution three here. This way jar files can still be dropped
into the ext directory, albeit the directory needs to be added to
the classpath on the command line. Unfortunately using a wildcard
is not possible in the manifest file. We change the calls in the
script files accordingly. This seems like a good compromise,
since no one will run the application manually typing the whole
commandline anyway.
This also does away with the splash screen, by the way. Again,
doesn't seem like a big loss, as I don't think it was ever shown
for the Authority.
Personally, I am not convinced that it is the best way, because
I don't really think that the use case of dropping whatever jar
files into the `ext` directory is a valid one that happened a lot.
This does not yet fix the client programs, which still use a
Launcher. Maybe for them a all-in-one Jar is a better solution.

A basic issue tracker styled as a hybrid of GitHub and BitBucket issues.
You may attach commits to an existing ticket or you can push a single
commit to create a *proposal* ticket.
Tickets keep track of patchsets (one or more commits) and allow patchset
rewriting (rebase, amend, squash) by detecing the non-fast-forward
update and assigning a new patchset number to the new commits.
Ticket tracker
--------------
The ticket tracker stores tickets as an append-only journal of changes.
The journals are deserialized and a ticket is built by applying the
journal entries. Tickets are indexed using Apache Lucene and all
queries and searches are executed against this Lucene index.
There is one trade-off to this persistence design: user attributions are
non-relational.
What does that mean? Each journal entry stores the username of the
author. If the username changes in the user service, the journal entry
will not reflect that change because the values are hard-coded.
Here are a few reasons/justifications for this design choice:
1. commit identifications (author, committer, tagger) are non-relational
2. maintains the KISS principle
3. your favorite text editor can still be your administration tool
Persistence Choices
-------------------
**FileTicketService**: stores journals on the filesystem
**BranchTicketService**: stores journals on an orphan branch
**RedisTicketService**: stores journals in a Redis key-value datastore
It should be relatively straight-forward to develop other backends
(MongoDB, etc) as long as the journal design is preserved.
Pushing Commits
---------------
Each push to a ticket is identified as a patchset revision. A patchset
revision may add commits to the patchset (fast-forward) OR a patchset
revision may rewrite history (rebase, squash, rebase+squash, or amend).
Patchset authors should not be afraid to polish, revise, and rewrite
their code before merging into the proposed branch.
Gitblit will create one ref for each patchset. These refs are updated
for fast-forward pushes or created for rewrites. They are formatted as
`refs/tickets/{shard}/{id}/{patchset}`. The *shard* is the last two
digits of the id. If the id < 10, prefix a 0. The *shard* is always
two digits long. The shard's purpose is to ensure Gitblit doesn't
exceed any filesystem directory limits for file creation.
**Creating a Proposal Ticket**
You may create a new change proposal ticket just by pushing a **single
commit** to `refs/for/{branch}` where branch is the proposed integration
branch OR `refs/for/new` or `refs/for/default` which both will use the
default repository branch.
git push origin HEAD:refs/for/new
**Updating a Patchset**
The safe way to update an existing patchset is to push to the patchset
ref.
git push origin HEAD:refs/heads/ticket/{id}
This ensures you do not accidentally create a new patchset in the event
that the patchset was updated after you last pulled.
The not-so-safe way to update an existing patchset is to push using the
magic ref.
git push origin HEAD:refs/for/{id}
This push ref will update an exisitng patchset OR create a new patchset
if the update is non-fast-forward.
**Rebasing, Squashing, Amending**
Gitblit makes rebasing, squashing, and amending patchsets easy.
Normally, pushing a non-fast-forward update would require rewind (RW+)
repository permissions. Gitblit provides a magic ref which will allow
ticket participants to rewrite a ticket patchset as long as the ticket
is open.
git push origin HEAD:refs/for/{id}
Pushing changes to this ref allows the patchset authors to rebase,
squash, or amend the patchset commits without requiring client-side use
of the *--force* flag on push AND without requiring RW+ permission to
the repository. Since each patchset is tracked with a ref it is easy to
recover from accidental non-fast-forward updates.
