Re: JVM apparently hanging


Hello again all...  I haven't tried all the other suggestions yet, but was able to get the Java stack where its hanging in the ZipInputStream constructor.  Does this look familiar to anyone?  Thanks!

Thread [main] (Suspended)
        Runtime.loadLibrary0(Class, String) line: 780   <-- seems to hang here.   Class is sun.security.action.LoadLibraryAction,
                                                                                                          and the String is "zip"
        System.loadLibrary(String) line: 834             // The value of the string argument here is "zip"
        LoadLibraryAction.run() line: 50 [local variables unavailable]
        AccessController.doPrivileged(PrivilegedAction) line: not available [native method]
        CRC32.<clinit>() line: 25 [local variables unavailable]
        ZipInputStream.<init>(InputStream) line: 26
        ClassHashtable.explodeArchive(String, byte[]) line: 112
