SunPKCS11 connection lost after Decrypt doFinal (noPadding) openjdk 8_232

[DEBORDEAUX Hubert]

Hello,
Following the update to OpenJDK 8_232, we did face a problem after a DECRYPT with no padding.
We use a SunPKCS11 provider linked to a Network HSM.
After a DECRYPT command (DES or AES) NOPADDING, we noticed the log : "Killing session (sun.security.pkcs11.P11Cipher.cancelOperation(P11Cipher.java:428)) active: 1"
All following commands failed with error : CKR_USER_NOT_LOGGED_IN

After a quick investigation, it looks like the fix JDK-8228565 done in P11Cipher.java is the root cause of this new behavior.
	....
	// Special handling to match SunJCE provider behavior
                if (bytesBuffered == 0 && padBufferLen == 0) {
                    return 0;
                }
	....
	} finally {
            		reset(doCancel);   // doCancel is true, so killSession is called.
        	}

This is a source code to reproduce the problem:
	SunPKCS11 p = new SunPKCS11(configName);           // config to Network HSM    
	p.setCallbackHandler(handler);    // Handler for password
        	Security.addProvider(p);
        
        	KeyStore.CallbackHandlerProtection chp =
                	new KeyStore.CallbackHandlerProtection(handler);
            	KeyStore.Builder builder = KeyStore.Builder.newInstance("PKCS11", p, chp);          
        	KeyStore keystore = builder.getKeyStore();
       	SecretKeyEntry entry = (SecretKeyEntry) keystore.getEntry("MyKeyAlias", null);         
        
        	Cipher cipher = Cipher.getInstance("DESede/CBC/NOPADDING", p.getName());                
        	IvParameterSpec ivParameterSpec = new IvParameterSpec(new byte[8]);  
        	// cipher a text
        	cipher.init(Cipher.ENCRYPT_MODE, entry.getSecretKey(), ivParameterSpec);
        	byte[] clearData = "clear text111111".getBytes();
        	byte[] cipheredData = cipher.doFinal(clearData);
           	// Decipher the result
        	cipher.init(Cipher.DECRYPT_MODE, entry.getSecretKey(), ivParameterSpec);         
        	byte[] clearTextResult = cipher.doFinal(cipheredData);
	// display the result        
	System.out.println(new String(clearTextResult));  // So far, no problem
        
              // Try another cipher
        	cipher.init(Cipher.ENCRYPT_MODE, entry.getSecretKey(), ivParameterSpec);
	byte[] clearData2 = "clear text222222".getBytes();
       	byte[] cipheredData2 = cipher.doFinal(clearData);
	// --> Failed with sun.security.pkcs11.wrapper.PKCS11Exception: CKR_USER_NOT_LOGGED_IN

Caused by: sun.security.pkcs11.wrapper.PKCS11Exception: CKR_USER_NOT_LOGGED_IN
	at sun.security.pkcs11.wrapper.PKCS11.C_EncryptUpdate(Native Method)
	at sun.security.pkcs11.P11Cipher.implUpdate(P11Cipher.java:581)

        
Workarounds:
	. use the SunPkcs11 jar file from openJDK 8_222
	. add a login after every decrypt commands
	. use PKCS5Padding when possible

Could you tell me if you can reproduce this problem and what is the best way for me to report it ?

Thanks you
Best Regards,
Hubert
