FULL PRODUCT VERSION :
Both JRE v1.6.0_21 and v1.6.0_22

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows 6.0.6002

EXTRA RELEVANT SYSTEM CONFIGURATION :
BC 1.45 for JDK6

A DESCRIPTION OF THE PROBLEM :
I have a working code worked from JRE v1.4.2_05 upto JRE v1.0.6_17,
 but throwing an exception from two latest JDK6 versions which are
 1.6.0_21 and 1.6.0_22. The exception is as follows:

java.security.InvalidKeyException: Illegal key size or default parameters
at javax.crypto.Cipher.a(DashoA13*..)
at javax.crypto.Cipher.init(DashoA13*..)
at javax.crypto.Cipher.init(DashoA13*..)

And the exception is thrown in the block of code included in the following:

public byte[] encrypt(byte[] clearText, String algName, String providerName, Key secretkey) {
        Cipher encipher = null;
        byte[] cipherText = null;

        // algName; "AES/ECB/PKCS5Padding"
        // providerName; "BC"
        // Key secretkey; "AES", 256, "BC"
        // clearText; byte[]

        try {
            encipher = Cipher.getInstance(algName, providerName);
            encipher.init(Cipher.ENCRYPT_MODE, secretkey); // <== This is the line WHERE the EXCEPTION thrown.
            cipherText = encipher.doFinal(clearText);
        } catch (Exception __ex) {
         __ex.printStackTrace();
        }
        return cipherText;
    }

It is not certain that the issue I am experiencing is caused by JDK or BC. Is anyone experiencing this kind of case? Or, is something I am missing? Thank you.

Best regards,

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Write a call to that method by providing three parameters as shown in
the report. One of the parameter is a symmetric key.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
a byte array of crypted text by encrypting the given clear text.

ACTUAL -
interrupted which was caused by an exception.


ERROR MESSAGES/STACK TRACES THAT OCCUR :
java.security.InvalidKeyException: Illegal key size or default parameters
at javax.crypto.Cipher.a(DashoA13*..)
at javax.crypto.Cipher.init(DashoA13*..)
at javax.crypto.Cipher.init(DashoA13*..)



REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
You can write a simple code to test it by generatin g symmetric key. But if
you needed one I can provide it. Please let me know.

CUSTOMER SUBMITTED WORKAROUND :
Removed both JDK/JRE 1.6.0_21 and JDK/JRE 1.6.0_22 to go back to the
JDK/JRE 1.6.0_17 which may require the end users to do as well.

Release Regression From : 6u17
The above release value was the last known release where this
bug was not reproducible. Since then there has been a regression.
