Hi,
[...]
But you mention that using the boot class loader as the parent class
loader for bundle class loaders causes problems for Nashorn. I fail to
see why that is.
I don't know the inner details but if you run this app
package samplenashornosgi;
import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;
import org.eclipse.equinox.app.IApplication;
import org.eclipse.equinox.app.IApplicationContext;
public class Application implements IApplication {
public static class SampleObject {
public SampleObject() {
System.err.println(I am:
+ this);
}
}
public Object start(IApplicationContext context) throws
Exception {
System.out.println(Hello RCP World!);
ScriptEngineManager mgr = new
ScriptEngineManager();
ScriptEngine engine =
mgr.getEngineByName(nashorn);
engine.eval(var SimpleObject =
Java.type('samplenashornosgi.Application.SampleObject'); new
SimpleObject(););
engine.eval(var SimpleObject =
Java.type('samplenashornosgi.Application.SampleObject'); var
SimpleSubClass = Java.extend(SimpleObject); new SimpleSubClass() {};);
return IApplication.EXIT_OK;
}
public void stop() {
// nothing to do
}
}
With the default setting you get:
Hello RCP World!
I am: samplenashornosgi.Application$SampleObject@2f8dad04

Re: [equinox-dev] Bundles remaining in life cyle Starting.
No sorry this is not right. Alex and Tom’s answer was correct. Please refer to section 4.4.6.2 of the OSGi Core R6 specification for details of the Lazy Activation Policy and its impact on bundle lifecycle. Unsatisfied imports such as in your example would cause a failure of resolution, leaving the bundle in INSTALLED state.
