Hi experts,
I am using org.eclipse.osgi_3.4.2.R34x_v20080826-1230.jar in order to start the OSGi environment in existing JVM. I use org.eclipse.core.runtime.adaptor.EclipseStarter.startup to initialize the OSGi instance with proper config.ini and plugins/*.jars.
However, I see this error on the first time I call the startup method inside the JVM. If I can the startup method again in the same JVM, It goes through. Can you let me know what can be wrong?
Thanks,
Tom
