Agreed; I've posted a BlenderRev corresponding to the current patch at:
http://cr.openjdk.java.net/~darcy/7007535.4/BR-7007535.html
Thanks. So now I can more readily see that the doc for Executable
isn't quite suitable for Constructor in a few places:
getDeclaringClass:
183 /**
184 * Returns the {@code Class} object representing the class or
interface
185 * that declares the method represented by this executable object.
186 */
For Constructor "method" should be "constructor". But I think, looking
at the terminology elsewhere that the above could be rewritten as:
"Returns the Class object representing the class or interface that
declares the executable represented by this object."
getParameterTypes:
219 * represented by this object. Returns an array of length
220 * 0 if the underlying method takes no parameters.
method -> executable
getGenericParameterTypes:
229 * parameter types, in declaration order, of the method
represented by
230 * this executable object. Returns an array of length 0 if the
231 * underlying method takes no parameters.
Again change to " the executable represented by this object".
And then: underlying method -> underlying executable
241 * parameter types of the underlying method, in declaration order
243 * if the generic method signature does not conform to the format
247 * types of the underlying method refers to a non-existent type
250 * the underlying method's parameter types refer to a parameterized
method -> executable
In fact do a search for "method" in Executable and most occurrences
should be changed to "executable".
Finally, in getModifiers, why delete the "as an integer. The Modifier
class should be used to decode the modifiers. " ?
BTW I also find the multiple "Specified by:" references to be quite
strange. There can only be one specification for a method.

This looks good to me but I agree with David that it's probably
important to look at the generated javadoc and specdiff output
before finalizing.

Thanks for the careful review; the @throws information still needs
its own {@inheritDoc}; I've uploaded a webrev with this and other

Please code review my JDK 8 changes for
7007535: (reflect) Please generalize Constructor and Method
http://cr.openjdk.java.net/~darcy/7007535.3
To summarize the changes, a new superclass is defined to capture
the common
functionality of java.lang.reflect.Method and
java.lang.reflect.Constructor.
That superclass is named "Executable" along the lines of
javax.lang.model.ExecutableElement, which models constructors
and methods in
the JSR 269 language model.
Both specification and implementation code are shared. To
preserve the right
@since behavior, it is common that in Method/Constructor the
javadoc for a
method will now look like:
/**
* {@inheritDoc}
* @since 1.5
*/
Unless they have fixed/changed javadoc (entirely possible) it
used to be that the above would not cause @throws declarations
for unchecked exceptions to be inherited - you have/had to
explicitly repeat them as:
@throws <exception-type> {@inheritDoc}
Yes, that would seem to be needed for some of the inherited
getters of generics info, which specify unchecked exception types.
Since Executable is being created in JDK 8, it would be
incorrect for
methods in that class to have an @since of 1.5; adding the
@since in
Method/Constructor preserves the right information.
In Executable.java, getAnnotation and getDeclaredAnnotations do
have "@since 1.5"-- oversight?
Yes; that was incorrect.
In Constructor.java and Method.java, getExceptionTypes has "@since
1.5", but that method has existed in those classes since 1.1.
Fixed.
In Executable.java:
216 /**
217 * Returns an array of {@code Class} objects that represent the
formal
218 * parameter types, in declaration order, of the method
219 * represented by this {@code Method} object. Returns an array
of length
220 * 0 if the underlying method takes no parameters.
221 *
222 * @return the parameter types for the method this object
223 * represents
At least "{@code Method}" needs to be generalized, and perhaps all
occurrences of "method"?
Corrected.
