Javadoc warnings for roles

[mosconi]

I encountered the following issues with Javadoc checking for missing comments enabled (for public elements only):

For a public role class with playedBy and missing Javadoc comment, 4 identical Warnings are generated: 3 for the role class and 1 for the base class. With a comment added, 3 of the Warnings remain (2 for role, 1 for base).

In case of a protected role class (which should give no Warning at all), there is 1 Warning for the role class. With comment added, the Warning remains.

I guess spurious warnings come from the generated role interface.

Shouldn't be too hard to fix.

My guess was right, but not complete. These generated elements are public and must be excluded from error reporting:

• role interface part
• cache field (reported against the playedBy position ;-)
• lifting constructors (role class position)

Test and fix are in r21654.
