NEW ISSUE: Signature of ComponentContext.cast() method

[Simon Nash <oasis@cjnash.com>]

TARGET: Java Common Annotations and APIs

DESCRIPTION: Signature of ComponentContext.cast() method

The signature of the ComponentContext.cast() method is currently
defined as follows:

<B, R extends ServiceReference<B>> R cast(B target)
     throws IllegalArgumentException;

The double parameterization does not make sense, because there
is nothing in the API that extends ServiceReference.

This form of the API was introduced when we had CallableReference
and ServiceReference.  At that time, the signature was:

<B, R extends CallableReference<B>> R cast(B target)
     throws IllegalArgumentException;

The double parameterization was useful then, because it allowed
either a ServiceReference or a CallableReference to be returned.

Now that CallableReference and ServiceReference have been merged,
it is confusing and redundant to have this double parameterization.

PROPOSAL:

Change the API signature to:

<B> ServiceReference<B> cast(B target) throws IllegalArgumentException;
