I'm not entirely sure if it's the same problem, but I'm having a similar problem.
I use a Java Web Start app which downloads its jar file via https. The app works fine in FF3.5.8. However, when attempting to run the app from FF3.6.3, I get the following: t...@test-desktop:~$ firefox java.security.ProviderException: Could not initialize NSS at sun.security.pkcs11.SunPKCS11.<init>(SunPKCS11.java:201) at sun.security.pkcs11.SunPKCS11.<init>(SunPKCS11.java:103) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:57) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:532) at sun.security.jca.ProviderConfig$3.run(ProviderConfig.java:262) at sun.security.jca.ProviderConfig$3.run(ProviderConfig.java:244) at java.security.AccessController.doPrivileged(Native Method) at sun.security.jca.ProviderConfig.doLoadProvider(ProviderConfig.java:244) at sun.security.jca.ProviderConfig.getProvider(ProviderConfig.java:224) at sun.security.jca.ProviderList.getProvider(ProviderList.java:232) at sun.security.jca.ProviderList.getService(ProviderList.java:330) at sun.security.jca.GetInstance.getInstance(GetInstance.java:157) at java.security.Security.getImpl(Security.java:696) at java.security.AlgorithmParameters.getInstance(AlgorithmParameters.java:130) at sun.security.x509.AlgorithmId.decodeParams(AlgorithmId.java:121) at sun.security.x509.AlgorithmId.<init>(AlgorithmId.java:114) at sun.security.x509.AlgorithmId.parse(AlgorithmId.java:381) at sun.security.x509.X509Key.parse(X509Key.java:168) at sun.security.x509.CertificateX509Key.<init>(CertificateX509Key.java:75) at sun.security.x509.X509CertInfo.parse(X509CertInfo.java:705) at sun.security.x509.X509CertInfo.<init>(X509CertInfo.java:169) at sun.security.x509.X509CertImpl.parse(X509CertImpl.java:1747) at sun.security.x509.X509CertImpl.<init>(X509CertImpl.java:196) at sun.security.provider.X509Factory.engineGenerateCertificate(X509Factory.java:107) at java.security.cert.CertificateFactory.generateCertificate(CertificateFactory.java:322) at sun.security.provider.JavaKeyStore.engineLoad(JavaKeyStore.java:763) at sun.security.provider.JavaKeyStore$JKS.engineLoad(JavaKeyStore.java:55) at java.security.KeyStore.load(KeyStore.java:1201) at sun.security.ssl.TrustManagerFactoryImpl.getCacertsKeyStore(TrustManagerFactoryImpl.java:221) at sun.security.ssl.TrustManagerFactoryImpl.engineInit(TrustManagerFactoryImpl.java:51) at javax.net.ssl.TrustManagerFactory.init(TrustManagerFactory.java:247) at net.sourceforge.jnlp.security.VariableX509TrustManager.<init>(VariableX509TrustManager.java:100) at net.sourceforge.jnlp.security.VariableX509TrustManager.getInstance(VariableX509TrustManager.java:282) at net.sourceforge.jnlp.runtime.Boot.main(Boot.java:178) Caused by: java.io.IOException: An incompatible version of NSS is already loaded, 3.7 or later required at sun.security.pkcs11.Secmod.isInitialized(Secmod.java:130) at sun.security.pkcs11.SunPKCS11.<init>(SunPKCS11.java:168) ... 35 more net.sourceforge.jnlp.LaunchException: Fatal: Launch Error: Could not launch JNLP file. at net.sourceforge.jnlp.Launcher.launchApplication(Launcher.java:462) at net.sourceforge.jnlp.Launcher$TgThread.run(Launcher.java:731) Caused by: java.lang.NullPointerException at net.sourceforge.jnlp.Launcher.launchApplication(Launcher.java:442) ... 1 more Caused by: java.lang.NullPointerException at net.sourceforge.jnlp.Launcher.launchApplication(Launcher.java:442) at net.sourceforge.jnlp.Launcher$TgThread.run(Launcher.java:731) [1]+ Done firefox t...@test-desktop:~$ If I instead download the jnlp file and run it manually with 'javaws app.jnlp', everything works fine. I noticed that FF3.6.3 ships with it's own libnss3.so (/usr/lib/firefox-3.6.3/libnss3.so), so I assume there is something about this library that is causing the problems. -- Java applet unable to load https://bugs.launchpad.net/bugs/553452 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
