Exception when formatting code which context annex which doesn't support IFormatter2

[philip-alldredge]

If an AADL model references an annex whose formatter doesn't support the IFormatter2 interface, an error occurs during formatting.

Not sure if this is considered an AGREE issue or an OSATE issue. However, this error did not occur in earlier versions of OSATE. Not sure when it was introduced.

Steps to Reproduce

1. Create an AADL model that uses an annex that doesn't implement IFormatter2 such as AGREE
2. Open the source file.
3. Select Source->Format

package format_issue
public
annex agree {**const test_constant : bool = true;**} ;

	system top
		annex agree {**
guarantee "Test Guarantee" : true;**} ;
	end top ;
end format_issue;

Environment

• OSATE Version: Latest develop.
• Operating System: Windows.
