Hi, While we test our WebStart app with Java 9 we noticed that a SecurityException is silently logged to the Java Webstart Console:
Exception in thread "Thread-13" java.lang.SecurityException: Sicherheitspaket-JAR-Datei kann nicht geprüft werden at jdk.deploy@9-ea/com.sun.deploy.util.SecurityBaseline.verifyJar(Unknown Source) at jdk.deploy@9-ea/com.sun.deploy.util.SecurityBaseline.access$200(Unknown Source) at jdk.deploy@9-ea/com.sun.deploy.util.SecurityBaseline$1.run(Unknown Source) at java.base/java.lang.Thread.run(Unknown Source) The app continues to work, we have not found any side effects yet. One conspicuous thing is that this is just logged after we call: java.util.logging.LogManager.getLogManager().readConfiguration(); I have not found any related open issue on https://bugs.openjdk.java.net All our JARs are signed and JNLP also request all-permissions. Tested with Java 9 b157 and Windows 7. The exception is not logged with Java 8 u121. Should we fill a report on bugreport.java.com for this ? Btw SecurityBaseline starts multiple threads, it would be great to give this threads a descriptive name. Thanks Reto
