Subject [jira] Commented: (HARMONY-1184) [classlib][crypto] compatibility: Cipher(null, null, "s") lead to NPE on RI and works silently on Harmony

Vladimir Ivanov commented on HARMONY-1184:
------------------------------------------

the test.java can be updated but it leads to increase test size:

        } catch (Exception e) {
            System.out.println("e1: " + e); 
        }
        try {
            System.out.println("res2 = " + new testCipher(new testCipherSpi(), null, "s"));

        } catch (Exception e) {
            System.out.println("e2: " + e); 
        }
        try {
            System.out.println("res2 = " + new testCipher(null, new testProvider(), "s"));

        } catch (Exception e) {
            System.out.println("e2: " + e); 
        }
    }
