java.lang.IllegalAccessError：尝试从类javax.crypto.Cipher访问类javax.crypto.Cipher $ Transform

Question

I'm trying to decrypt a string using AES and I'm using jce.jar to do it.

I have the following method to decrypt.

 public String decrypt(String strToDecrypt) {
        try {
            Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5PADDING");
            cipher.init(Cipher.DECRYPT_MODE, secretKey);
            setDecryptedString(new String(cipher.doFinal(Base64
                    .decodeBase64(strToDecrypt))));
        } catch (Exception e) {
            System.out.println("Error while decrypting: " + e.toString());
        }
        return null;
    }

But while trying to decrypt I got the following error.

java.lang.IllegalAccessError: tried to access class javax.crypto.Cipher$Transform from class javax.crypto.Cipher

I'm using java_sdk_1.7.0 version. Is it an issue with my sdk version? Does anyone have idea on this?

This crypto error is coming due to conflicting jce.jar in the jms and the openjdk. Issue was resolved by commenting out this line in standalone.xml:

<--module name="org.jboss.genericjms.provider" slot="main"-->
