Add assertion on expected exception when adding a try/catch

[vmassol]

For example the following test was added:

    @Test(timeout = 10000)
    public void testRSAEncryptionDecryptionProgressive_failAssert2() throws Exception {
        try {
            Cipher cipher = factory.getInstance(true, AmplBcRsaOaepCipherFactoryTest.publicKey);
            cipher.update(AmplBcRsaOaepCipherFactoryTest.input, 0, 17);
            cipher.update(AmplBcRsaOaepCipherFactoryTest.input, 17, 1);
            cipher.update(AmplBcRsaOaepCipherFactoryTest.input, 18, ((AmplBcRsaOaepCipherFactoryTest.input.length) - 18));
            byte[] encrypted = cipher.doFinal();
            cipher = factory.getInstance(false, AmplBcRsaOaepCipherFactoryTest.privateKey);
            cipher.update(encrypted, 0, 65);
            cipher.update(encrypted, 65, 1);
            cipher.update(encrypted, 66, ((encrypted.length) - 66));
            cipher.doFinal();
            CoreMatchers.equalTo(AmplBcRsaOaepCipherFactoryTest.input);
            cipher = factory.getInstance(true, AmplBcRsaOaepCipherFactoryTest.privateKey);
            cipher.update(AmplBcRsaOaepCipherFactoryTest.input, 0, 15);
            cipher.update(AmplBcRsaOaepCipherFactoryTest.input, 15, 1);
            encrypted = cipher.doFinal(AmplBcRsaOaepCipherFactoryTest.input, 16, ((AmplBcRsaOaepCipherFactoryTest.input.length) - 16));
            cipher = factory.getInstance(false, AmplBcRsaOaepCipherFactoryTest.publicKey);
            cipher.update(encrypted);
            cipher.doFinal();
            CoreMatchers.equalTo(AmplBcRsaOaepCipherFactoryTest.input);
            cipher.doFinal();
            CoreMatchers.equalTo(AmplBcRsaOaepCipherFactoryTest.input);
            org.junit.Assert.fail("testRSAEncryptionDecryptionProgressive should have thrown GeneralSecurityException");
        } catch (GeneralSecurityException eee) {
        }
    }

It would be nice to improve this on 2 aspects:

• name the exception "expected" instead of "eee". This a JUnit best practice
• assert the exception message
