Re: [sca-j] ISSUE-168: Conversion rules for property values are notspecified

Hi Simon,

Referring to the other thread [1], I see now that you're focusing on the XML to Java type coercion, and now I'm sure we're talking about different aspects of the problem. I was focused on the Java to Java aspect introduced by the proposal to Issue 139, and you've focused on on the Component to implementation problem. Section 8 of the JCI spec does describe the Java to componentType mapping as based on JAXB. Why doesn't this address your concern?

Resending with "NEW ISSUE" tag in the email subject line.

TARGET: Java Common Annotations and APIs

DESCRIPTION: Conversion rules for property values are not specified

The @Property annotation allows component implementations to
define SCA properties of any Java type.  However, there are no
rules stated for how property values specified in component
definitions are converted to the Java type of the property,
or what happens if this conversion fails.

PROPOSAL:

The conversion rules should follow the JAXB rules for mapping
XML to Java.

Suitable text should be added to section 2.1.5 describing how
property value conversions are performed and what happens if
the conversion fails.
