Hi Michaël,
Thanks for your comments and links to docking and plugin
libraries/frameworks.
> is infonode totally free and opensource ?
InfoNode Docking Windows is under GPL. It looks quite good (as one can see
in my screenshots) and has a nice API.
One idea I had which may be related to the plugin management is that
> OpenJUMP should be able to record plugin actions in macros.
Here's my basic idea.
void execute(Map<String, Object> macroOptions) {
Map<String, Object> optionsForExecute = null;
if (macroOptions) {
optionsForExecute = macroOptions);
} else {
optionsForExecute = Dialog.showAndReturnUserSelection()
// save optionsForExecute with MacroRecorder.
}
// use optionsForExecute to do something.
}
I'm afraid by the addition of a new library for each single enhancement.

Here are some greps listing all dependencies between source files and
jar-files in OpenJUMP.

I played around a bit with it and ended up removing 50% of the dependencies.
The lend me to the idea of spliting OpenJUMP into several jars:
openjump-core.jar, openjump-scripting.jar (jython, bsh), openjump-raster.jar
(jai, ...), openjump-gml-svg-sld.jar (batik, xml-apis) and
openjump-postgis.jar (postgresql).
Just a small idea to minimize dependencies for openjump-core.jar.

I like the idea of keeping the core in Java and create a new project file
(thus a separate JAR-file) for the UI. The source code of the UI could be in
Java and Groovy.
Some words to Groovy: Groovy acts the _same_ as Java (i. e. it compiles to
.class files), just without unneccessary ceremony. I use it throughout my
OpenJUMP extension (no single line is in Java). You even can rename the
extension of a .java file into .groovy and it will compile fine (i. e. java
syntax is actually a subset of groovy syntax).
Groovy can also used for scripting in applications (just like Jython, JRuby
or BeanShell). But I don't prefer to do that with Groovy.
