And I found out the problem: The thread died because some jar wasn't in the path. This is bad for a thread to die silently, and it is a bug in Java, but oh well, I got that fixed. Now I have the whole thing working as long as the password is correct for the login. This is big progress. But when the password is incorrect, I get: Exception in thread "main" java.lang.reflect.UndeclaredThrowableException | at $Proxy0.time(Unknown Source) | at mypackage.CLIConnectivityTest.authorizedTest(CLIConnectivityTest.java:59) | at mypackage.CLIConnectivityTest.main(CLIConnectivityTest.java:70) | Caused by: java.lang.ClassNotFoundException: [Ljava.lang.StackTraceElement; | at java.net.URLClassLoader$1.run(URLClassLoader.java:200) | at java.security.AccessController.doPrivileged(Native Method) | ............. | How should my code handle this? Should I really catch UndeclaredThorwableExceptions all over the place? Surely there must be a more specific "you are not authorized" type of exception that could be thrown?
