IllegalAccessError error on startup

[jbone]

I have an Mbean which starts up a simple socket listener. The listener uses SSL, and every so often it doesnt start up right. The error I get is the following:

2003-07-18 11:19:28,069 ERROR [STDERR] java.lang.IllegalAccessError: try to access method com.sun.net.ssl.TrustManagerFactorySpi.engineInit(Ljava/security/KeyStore;)V from class com.sun.net.ssl.TrustManagerFactory

2003-07-18 11:19:28,079 ERROR [STDERR] at java.lang.Thread.run(Thread.java:479)


A sample of the code I'm using follows:

public class SocketServer implements SocketServerMBean, Serializable {
private static final Logger log = Logger.getLogger("SocketServer.class");

static final int PORT=8686;
private String JNDIName="";

SocketListener currentListener;

public void create() throws Exception {
currentListener = new SocketListener(PORT);
}

public void start() throws Exception {
currentListener.start();
}

public void stop() {
currentListener.stop();
}

public void destroy(){
currentListener = null;
}

}


public class SocketListener implements Runnable, Serializable {

...

public SocketListener(int port){
//set up SSL
java.security.Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
...
}

private void setSSL(){
try {
SecureRandom secureRandom = new SecureRandom();
secureRandom.nextInt();

KeyStore serverKeyStore = KeyStore.getInstance( "JKS" );
serverKeyStore.load( new FileInputStream( "server.private" ), PASSWORD.toCharArray() );

clientKeyStore = KeyStore.getInstance( "JKS" );
clientKeyStore.load( new FileInputStream( "client.public" ), "public".toCharArray() );

TrustManagerFactory tmf = TrustManagerFactory.getInstance( "SunX509" );
tmf.init( clientKeyStore );

KeyManagerFactory kmf = KeyManagerFactory.getInstance( "SunX509" );
kmf.init( serverKeyStore, PASSWORD.toCharArray() );

sslContext = SSLContext.getInstance( "TLS" );
sslContext.init( kmf.getKeyManagers(), tmf.getTrustManagers(), secureRandom );

SSLServerSocketFactory sf = sslContext.getServerSocketFactory();
ss = (SSLServerSocket)sf.createServerSocket( port );
}
catch (Exception e){e.printStackTrace();}
}



}

Any ideas?
