Re: [sca-j] JAVA-139: Proposed resolution

[Simon Nash <oasis@cjnash.com>]

Dave,
I did think about this when writing the proposal.  The coercion
rules for the defaultValue attribute (for properties of any type)
should be the same as the existing coercion rules for a property
value specified in the component definition (for properties of
any type).

Unfortunately, I was unable to find any text in the Java specs
describing the coercion rules for property values specified in
the component definition, or what happens if coercion of these
values fails.  I did not think it was within the scope of JAVA-139
to add new text describing these existing coercion rules for
component property values.

I think the best approach is to raise an issue for the lack of
existing coercion rules for property values.  When this is resolved
by adding suitable text, I can update the proposal for JAVA-139 to
refer to this added text.

To answer your questions: This proposal does apply to properties
of all types, and I do still think we need to do this.
