Bug Description

Codec.hexStringToByte(String hexString) throws an exception for a valid String.

The following test case
  String s = "test";
  byte[] s1bytes = Codec.hexStringToByte( Codec.byteToHexString( s.getBytes() ) );
  String s1 = new String( s1bytes );
  assertEquals( s, s1 );
fails with
java.lang.StringIndexOutOfBoundsException: String index out of range: 10
 at java.lang.String.substring(String.java:1934)
 at play.libs.Codec.hexStringToByte(Codec.java:115)

I am using version 1.0.1.
Since you already have commons codec and bouncycastle in the 3rd party libraries I suggest using one of them for these operations.
