Other Improvements

Base64

We no longer have to use sun.misc.BASE64Encoder or org.apache.commons.codec.binary.Base64. No we can use java.util.Base64 class. This is because the internal APIs were encapsulated and are no longer available.

byte[] toEncode = "dummy string".getBytes();

byte[] encoded = Base64.getEncoder().encode(toEncode);
String encodedString = new String(encoded);

Assert.assertEquals("ZHVtbXkgc3RyaW5n", encodedString);

Unsafe

Unsafe is meant to be used only by internal core Java classes.
