"Extra data detected in stream" - pls make it easier to handle

[ralfhauser]

As per #2360 , please add a "@deprecated" with the explanation to use an InputStream instead as constructor argument

 public CMSSignedData(
        byte[] sigBlock)
        throws CMSException

or clean it by

    asn1In = new ASN1InputStream(is)
   ASN1Primitive asn1Object = asn1In.readObject()
   byte[] encoded = asn1Object.getEncoded();
   return encoded

for example with a static
public static CMSSignedData getCMSSignedDataByCleandBA(byte[] sigBlock) {

[ralfhauser]

or do it directly yourself

public CMSSignedData(
        byte[] sigBlock)
        throws CMSException {
     this(new ByteArrayInputStream(sigBlock));
}
