java spec defines following behavior of the javax.crypto.spec.SecretKeySpec constructor:

--- SecretKeySpec(byte[] key,int offset,int,len,String algorithm)
"...
Throws:
IllegalArgumentException - if algorithm is null or key is null, empty, or too short, i.e. key.length-offset.
ArrayIndexOutOfBoundsException - is thrown if offset or len index bytes outside the key."

However the runtime throws "java.lang.IllegalArgumentException: Invalid offset/length combination" when len/offset are invalid.
