This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
In the above code I am not getting the same original byte array after converting into String. If I use charsetBane "UTF-16BE", I am getting the original bytes. But in my program I am always using UTF-16LE in all the places. Is there any error or known bug with java unicode encoding using UTF-16LE. Please help me if anyone faced similar kind of issue and I really appreciate it.

Correct. A byte array of binary data generated by the AES encryption algorithm is not the same thing as a byte array of UTF-16LE encoded characters. Some of the bytes will be trimmed to fit the UTF-16LE codepage and you end up with garbage.
