/**

 * @library /test/lib
 * @run testng RemoveDifferentKeyAlgBlockFile
 * @summary Checks that if a signed jar file is signed again with the same
 * signer name and a different algorithm that the signature block file for
 * the previous signature is removed. Example: the jar had META-INF/A.SF and
 * META-INF/A.RSA files and is now signed with DSA. So it should contain
 * an updated META-INF/A.SF and META-INF/A.DSA and the META-INF/A.RSA should
 * be removed because not valid any longer.
