the halt of keyStore.store(OutputStream,String password)

[bbskill]

Hi , all,

I want to use the keyStore to save the certificate from server through 
SSL Socket(Jessie with libgcj4.2 ). But when I use
keyStore.store(OutputStream,String password) function, my application 
will halt for quite a while. and finnally got a exception
when communicating with the server.
Java.io.IOException

gnu.javax.net.ssl.provider.SSLSocket.startHandshake(SSLSocket.java:521)
My code seens below : MyX509TrustManager.java :
     public void checkServerTrusted(X509Certificate[] chain, String 
authType)
            throws CertificateException {
                        // Add Chain to the keyStore.
                    for (int i = 0; i < chain.length; i++)
                        keyStore.setCertificateEntry(chain[i].getIssuerDN()
                                .toString(), chain[i]);
                       // save to the file
                       keyStore.store(new FileOutputStream(keyStorePath)
                                    , keyStorePassword);
                      tmf.init(keyStore);   //TrustManagerFactory is to 
be initialized again
                      tm = tmf.getTrustManagers()[0];   // reget the 
TrustManager.
}

And I removed this line : keyStore.store(new 
FileOutputStream(keyStorePath) , keyStorePassword), and all the things 
gone. My application
worked fine with the server.

I use libgcj4.2 in Linux/2.6/gnome2.14, and I don'k know why, the same 
code works fine in sun jdk1.6;

Thanks for your any help.

Best Regards.
Jimmy.
