[#3376] Use IllegalArgumentException as replacement for NPE as stated in javadocs

Browse Source 
Motivation:

SSLEngine specifies that IllegalArgumentException must be thrown if a null argument is given when using wrap(...) or unwrap(...).

Modifications:

Replace NullPointerException with IllegalArgumentException to match the javadocs.

Result:

Match the javadocs.
