The conclusion we reached at our meeting for making up the Eclipse grant
proposal was that annotations were one of the two Java 1.5 features
that would require extensive work throughout all of Soot (the other
such feature, to a lesser extent, was generics). Have we heard about
the Eclipse grant yet? In particular, annotations require modifications
to all the IRs to include annotations and propagate them to other IRs
(though we may be able to leverage the tagging framework for some of
this), to the coffi class file parser, to the jasmin assembler, to
the IR output code, to the Jimple IR parser, to the decompiler to
output them, to Polyglot to parse them and typecheck them, and to j2j
to convert them from Polyglot to Jimple. We haven't had a chance yet
to determine how difficult each of these steps will be (it depends on
details of how annotations are implemented in class files), but there
are many steps. I don't know what exact promises we made in the Eclipse
proposal.

In addition, for annotations to be useful, Soot needs to be able to
read and write class files in the Java 1.5 classfile format. This will
probably require some of the "simple" 1.5 features (such as enums) to
also be implemented.

A basic plan of attack for the Java 1.5 features is on the wiki:
http://svn.sable.mcgill.ca/wiki/index.php/JavaOneFivePlan

We tentatively decided that Jennifer would work on these features. This
Winter term (Jan-Apr), she has a full course load and is helping Laurie
teach.
