Hi everyone, I work for a company that have been using Felix with Java Web Start in a core product for several years. Thus, we have recently encountered the security warning discussed on this mailing list and in the issue below:
https://issues.apache.org/jira/browse/FELIX-4281 I have been looking into this now and then for the past few weeks, and I have a small toy-example that reproduces the problem. For a while I thought we had a problem somewhere in our code, or maybe something was wrong with Java Web Start (that would not the the first time ...), but I am beginning to think we're dealing with a bug in Felix. I do not understand all aspects of the problem, but I have found that removing a few lines of code from org/apache/felix/framework/ExtensionManager.java makes the problem go away: // Felix.m_secureAction.addURLToURLClassLoader(Felix.m_secureAction.createURL( // Felix.m_secureAction.createURL(null, "http:", extensionManager), // "http://felix.extensions:9/";, extensionManager), // Felix.class.getClassLoader()); The code seems to have something to do with OSGi extension bundles. We don't use them anyway. Thus, we can live with that fix. However, this is probably not a solution for everyone. The code I have removed adds the special "http://felix.extensions:9/"; URL to an URLClassLoader. It seems that this URL causes problems when Java Web Start performs security checks. I got suspicious about this when I got the following in my Java Web Start log: security: JAVAWS AppPolicy Permission requested for: http://felix.extensions:9/ ruleset: finding Deployment Rule Set for title: null location: null main location: http://felix.extensions:9/ main version: null isArtifact: true The main location does not look like the main location of other jar files in the log. That made me stumble upon an old issue from 2011 (https://issues.apache.org/jira/browse/FELIX-2780). In the comments Ingo Bauersachs suggested to replace "http" with some other protocol descriptor. I have tried to do the same, but it does not remove the security warnings. However, when I remove the lines as suggested above, my log looks like this: Security: JAVAWS AppPolicy Permission requested for: http://localhost:8000/felix.jar ruleset: finding Deployment Rule Set for title: Webstart Felix location: http://localhost:8000/wsf.jnlp main location: http://localhost:8000/felix.jar main version: null isArtifact: true I have tried looking into org/apache/felix/framework/util/SecureAction.java to see if I would somehow come up with a less radical fix. I have failed to do so until now, but maybe someone with a deeper knowledge of Felix could figure something out? My small toy program is a very simple one. It looks like this: public static void main(String[] args) throws Exception { System.out.println("Bootstrapper running"); System.out.println("Press '5' to enable more logging in your " + "Java Webstart Console (you've got 3 seconds)."); for(int i = 3; i > 0; i--) { Thread.sleep(1000); System.out.println(i); } System.out.println("Starting Felix"); HashMap<String,String> cfg = new HashMap<String,String>(); //cfg.put("felix.service.urlhandlers", "false"); // tried this: it doesn't make a difference. Felix f = new Felix(cfg); f.init(); // <--- this is where the warning is shown f.start(); f.stop(); System.out.println("It worked!"); } My JNLP file looks like this: <?xml version="1.0" encoding="UTF-8"?> <jnlp spec="1.0+" codebase="http://localhost:8000/"; href="wsf.jnlp"> <information> <title>Webstart Felix</title> <vendor>Martin Rytter</vendor> <offline-allowed/> </information> <security> <all-permissions /> </security> <resources> <j2se version="1.7.0+" href="http://java.sun.com/products/autodl/j2se"/> <jar href="wsf.jar" main="true" /> <jar href="felix.jar" /> </resources> <application-desc name="Webstart Felix" main-class="wsf.Main" /> </jnlp> I use a JNLP template because this is what we do in our product. However, signing the plain old JNLP file would probably cause the same problem. My template looks like this: <?xml version="1.0" encoding="UTF-8"?> <jnlp spec="1.0+" codebase="*" href="*"> <information> <title>*</title> <vendor>Martin Rytter</vendor> <offline-allowed/> </information> <security> <all-permissions /> </security> <resources> <j2se version="1.7.0+" href="http://java.sun.com/products/autodl/j2se"/> <jar href="wsf.jar" main="true" /> <jar href="felix.jar" /> </resources> <application-desc name="*" main-class="wsf.Main" /> </jnlp> The recent security updates prefer if you add some special entries to the manifests of all your jar files. Thus, I add the following entries to the felix.jar and wsf.jar: Codebase=* Permissions=all-permissions Trusted-Only=true Both my jar files are signed using our company's keystore. I you have trouble reproducing what I did above, I could remove the keystore from my example and share it with you. It would probably be possible to do the same with a self-signed certificate, but I have not tried that yet. I discovered the problem when using org.apache.felix.framework-4.0.3, but I have made my toy-example with the more recent org.apache.felix.framework-4.2.1. The two versions of Felix seem to have the same problem. I have tried to get a deeper understanding of the problem by making a threaddump when the security warning is shown. I didn't learn a lot from that, but I suspect someone with deep knowledge of Java Web Start or Felix would. The threaddump looks like this: Dump thread stack ... ---------------------------------------------------- 2013-10-25 09:01:25 Full thread dump Java HotSpot(TM) 64-Bit Server VM (24.45-b08 mixed mode): "FelixDispatchQueue" prio=10 tid=0x00007f0924092000 nid=0x14f9 in Object.wait() [0x00007f099a68b000] java.lang.Thread.State: WAITING (on object monitor) at java.lang.Object.wait(Native Method) -

I will try to take my toy-example-solution and integrate it into our real system next week. We can probably live with that for a while, as we don't use extension bundles for anything. However, we would much prefer a more correct solution. Thus, if you need more information from me, I will be happy share whatever I know. I will also be happy to test any solution the Felix team might come up with on our system. Oh, btw. Thanks to everyone on the Felix team. We love your product!
