I recently released 
Drombler FX v0.3. 
Drombler FX is 
a modular Rich Client Platform for JavaFX based on OSGi and Maven (POM-first).
With this release the 
Docking Framework and the 
Context Framework have been moved from the OSGi-based RCP 
Drombler FX to the 
Drombler Commons library collection, which can be used inside and outside of an OSGi platform.
This allows you to use these frameworks even if you don't want to use 
Drombler FX, yet, for some reason. 
Note that the declarative, annotation based programming model is still only supported by 
Drombler FX. But using the libraries from 
Drombler Commons you can use the 
Docking Framework programmatically like this:
Add a 
DockingPane to the scene and initialize the 
ContextManager and the 
DockingManager.
The 
DockingPane splits up its content area into any number of 
Docking Areas. The 
Docking Areas can be resized using the dividers. Each 
Docking Area can hold any number of 
Dockable Panes, which are layed out as Tabs.
The ContextManager and the DockingManager manage the 
Acitve Context and the 
Application Context depending on the currently open and active 
Dockable Panes.
Register a 
Docking Area:
Initialize the 
DockablePreferencesManager and register the default 
DockablePreferences for each 
Dockable Pane type (here: 
LeftTestPane which should be docked into the 
Docking Area with ID 
"left"):
Add a 
DockablePane (here: 
LeftTestPane) to the 
DockingPane:
You can find a complete sample 
here.
Note that the 
Docking Framework is still in its early stages and advanced features such as drag'n'drop 
Dockable Panes don't work yet. Currently it supports:
- Register Docking Areas and visualize them by adding TabPanes to a custom multi-SplitPane.
- Add Dockable Panes to Docking Areas using a logical Docking Area ID.
- Calculate the minimal required SplitPanes depending on the sparse definition of Docking Areas and the currently open Dockable Panes.
Here you can find a list of currently known issues and enhancement requests.
Especially have a look at the 
API issues. Although I took the opportunity and invested a lot of effort to clean up the API in the process of moving the framework from 
Dromber FX, where the programmatic API was in a hidden package, to 
Drombler Commons, where a part of the programmatic API has now been published, I'm still not 100% satisfied with the current state. Other opinions are highly welcome!
Please feel free to vote, comment and/ or file new issues.
For more information on the 
Context Framework have a look at the 
wiki.

The following table provides you an overview of the different 
Drombler components, links to the modules, which are available from Maven Central, and links to the Javadocs.

Note that since JavaFX 8 isn't 100% backwards compatible with JavaFX 2.x, this release still only works with Java SE 7/ JavaFX 2.x.
I'm already working on 
upgrading Drombler FX and 
Drombler Commons to Java SE 8/ JavaFX 8, however, and it will likely make it into the 
next release. Stay tuned!
