Summary: jEdit 5.1.0 on Mac OS X with Java 7

Initial Comment:
This is jEdit as Mac OS X application bundle, based on current Java 7
from Oracle, instead of the dead an buried Java 6 from Apple.  Current
7u40 even supports Retina displays.

The main application launcher is http://java.net/projects/appbundler
from Oracle, see its appbundler-1.0.jar (it contains an ant task to do
the bundling on some running Mac OS X system, but the directory layout
and Info.plist file can be created by other means as well, on any
platform.)

The resulting directory layout of jEdit.app is as follows, based on
existing jEdit-5.1.0 for Mac OS X:

  Contents/MacOS/JavaAppLauncher  # main launcher from appbundler-1.0.jar
  Contents/Info.plist  # handwritten version based on ant output
  Contents/Java/   # jedit.jar and all the rest (formerly Resources/Java/)
  Contents/PlugIns/jdk/  # full jdk, or trimmed version produced by appbundler ant task
  Contents/Resources/icon.icns  # regular jEdit icon as before
  Contents/Resources/file.icns  # presently unused, no file types yet

The appbundler ant task takes a locally installed jdk as a starting
point to bundle a subset of it into the application.  This is now the
official policy of Oracle and Apple.  Note that plain jre does not
work here at the moment -- reasons unknown.  For demonstration
purposes I've made Contents/PlugIns/jdk a symlink to some jdk found
locally on the system, but an official version should include a
self-contained copy of it.

Moreover, note that appbundler-1.0 does not handle file types yet.
There is a fork of the Oracle project here
https://bitbucket.org/infinitekind/appbundler that does that, apart
from other improvements, but I did not manage to make this work yet.

Further required changes on the jEdit side:

  * Debug.ALTERNATIVE_DISPATCHER = false (always).  Maybe even remove
    that alternative key event dispatcher altogether.  It is not
    required in Java 6, and breaks Java 7.

  * Brushing up the MacOSX plugin, maybe dismantling some old
    workarounds.  In fact, it would be preferable to get Mac OS X
    application support directly into jedit.jar -- this works by
    dynamic method invocation via "reflection", so jEdit will be
    compilable and runnable on all platforms.

Message:
Still having same  troubles (requiring install of java6), even with
jarbundler 2.2. A new way of packaging the dmg is probably a good idea.

Message:
I noticed JarBundler has released a v 2.2.0 now. I will see if we can make
jEdit work with that.
