ISSUE --encrypt key operation with BCFIPS Provider and using XML-Sec library

Hi Team,

We are facing the following issue while performing encrypt key operation
with BCFIPS Provider and using XML-Sec library

Following is the code snippet:

            // Generate a traffic key
            javax.crypto.KeyGenerator keyGenerator =
KeyGenerator.getInstance("AES", "BCFIPS");
            keyGenerator.init(256, sRandom);
            javax.crypto.SecretKey dek = keyGenerator.generateKey();


            java.security.PublicKey pk = jsCert.getPublicKey(); //this is
publickey of cert generated with 1024 key length

            org.apache.xml.security.encryption,XMLCipher cipher = null;
             cipher = org.apache.xml.security.encryption.
XMLCipher.getProviderInstance("http://www.w3.org/2009/xmlenc11#rsa-oaep",
"BCFIPS", org.apache.xml.security.c14n.Canonicalize.ALGO_ID_C14N_PHYSICAL,
                        "http://www.w3.org/2001/04/xmldsig-more#sha384");
          * // The above line
will basically call javax.crypto.Cipher.getInstance("RSA/ECB/OAEPPadding",
"BCFIPS"); to fetch the XMLCipher Instance*

            cipher.init(XMLCipher.WRAP_MODE, pk);
            org.apache.xml.security.encryption.EncryptedKey encryptedKey =
null;

            encryptedKey = cipher.encryptKey(xmlDoc, dek, "
http://www.w3.org/2009/xmlenc11#mgf1sha384", null);// *I am facing
exception( javax.crypto.IllegalBlockSizeException: Unable to wrap key:
input data too long.) here *

*Our Observations:*
*When using 1024 key length certificate, 1024+(key algorithm length)+(block
algorithm) > 1600, we are getting this error*
*For example 1024(certificate length)+256(key algorithm length)+384(block
algorithm length)  which is greater than  1600, we are facing this issue*
*When using 1024+ 256 +256+ 256 which is less than 1600 we are not facing
this issue*

Is our observation valid?

Could you please help us to understand any limitations while using
rsa-oaep  encryption alogrithms. Also please let us know if you have any
further information or reproduction.
