API changes for ports outside the main tree
Cooja API changes for plugins outside the main tree
Update from JDOM 1 to JDOM 2
JDOM was upgraded from version 1 to version 2 (#784). This requires some source code updates, but since Cooja uses such a small subset of the JDOM API, the update can be done automatically with the command:
find <directory> -name \*.java -exec perl -pi -e 's#import org.jdom.#import org.jdom2.#g' {} \;
Avoid starting the AWT thread in headless mode
Cooja will no longer start plugins that extend VisPlugin
in headless mode
to avoid starting the AWT thread. Plugins that should run in both GUI mode
and headless mode need to be updated to keep the JInternalFrame internal.
Examples for PowerTracker and other plugins can be found in the PR
(#261).
