I'm using OSGi (Apache Felix) to develop my application. The bundle's
activator is as follows:
@Override
public void start(BundleContext context) throws Exception {
new Thread(() -> Application.launch(Desktop.class), "JavaFX Desktop
launcher").start();
}
@Override
public void stop(BundleContext context) throws Exception {
Platform.exit();
}
The new Thread() is because Application.launch blocks the thread (can
it be avoided?).
However, the main problem is when I stop a bundle, do an update and
try to start it again. Unless I quit the entire OSGi container I get
the following stacktrace:
g! Exception in thread "JavaFX Desktop launcher"
java.lang.IllegalStateException: Application launch must not be called
more than once
at
com.sun.javafx.application.LauncherImpl.launchApplication(LauncherImpl.java:162)
at
com.sun.javafx.application.LauncherImpl.launchApplication(LauncherImpl.java:143)
at javafx.application.Application.launch(Application.java:191)
While I understand this in a regular situation, it is kind of annoying
in a environment such as OSGi. I would have thought that calling
Platform.exit() in the activator's stop() method would have done the
trick, but obviously it doesn't.
Is there a way to completely stop the JavaFX framework in the stop()
method so that a subsequent call to start() will be capable of
starting a new application?
