Init plugins' AllRequestFilters, even if they are loaded after startup

When installing a plugin with AllRequestFilters after Gerrit has been
started up, the filter's doFilter is called as expected. But the
filter's init method is never called, as FilterProxy did not keep
track of which filters have been around when its own init got called.

This lack of calling init, breaks the Filter contract, and makes the
javamelody plugin throw NPEs [1] for each request when installing it
in a running Gerrit. While restarting Gerrit renders the javamelody
plugin working, the root problem is the missing call to the
filter's init.

Hence, we make FilterProxy call init for plugins that did not get
initialized when FilterProxy itself got initialized. Thereby, the
javamelody plugin can be loaded directly into a running Gerrit again.

Gerrit Code Review

Gerrit is a code review and project management tool for Git based projects.

Objective

Gerrit makes reviews easier by showing changes in a side-by-side display, and allowing inline comments to be added by any reviewer.

Gerrit simplifies Git based project maintainership by permitting any authorized user to submit changes to the master Git repository, rather than requiring all approved changes to be merged in by hand by the project maintainer.

Documentation

For information about how to install and use Gerrit, refer to the documentation.

Source

Our canonical Git repository is located on googlesource.com. There is a mirror of the repository on Github.

Reporting bugs

Please report bugs on the issue tracker.

Contribute

Gerrit is the work of hundreds of contributors. We appreciate your help!

Please read the contribution guidelines.

Note that we do not accept Pull Requests via the Github mirror.

Getting in contact

The instruction how to configure GerritForge/BinTray repositories is here

On Debian/Ubuntu run:

NOTE: release is a counter that starts with 1 and indicates the number of packages that have been released with the same version of the software.

On CentOS/RedHat run:

    yum clean all && yum install gerrit-<version>[-<release>]

NOTE: release is optional. Last released package of the version is installed if the release number is omitted.
