-------------------------------------

Hello

I was wrong in my first description. NPE is thrown when the resource doesn't exist. URL.openConnection() must throw IOException instead. The source code of the atached testcase is:

{code:java}
package com.mwaysolutions.gofer2.sandbox2;

import java.net.URL;

import org.osgi.framework.Bundle;
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;

public class SandboxActivator implements BundleActivator {

	@Override
	public void start(final BundleContext context) throws Exception {
		final Bundle bundle = context.getBundle();
		final URL baseUrl = bundle.getEntry("com/mwaysolutions/gofer2/sandbox2/");
		final URL url = baseUrl.toURI().resolve("not-existing-resource").toURL();
		url.openConnection();
	}

	@Override
	public void stop(final BundleContext context) throws Exception {

	}

}
{code}
