[Soot-list] How to read Java 5 annotations?

[Bernhard Berger]

Hi Marc-André,

all the annotations can be found within Soot. In my opinion, there is an
imperfection regarding class-tags used within annotations but all static
information can be found after loading the classes from bytecode (never
tried to load from Jimple).

The problem I've had in a project with the mentioned class tags
(@Foo(param = Type.class)) is the following: The parameter is converted
to a soot.tagkit.AnnotationClassElem instance and the type is stored as
a string value (of the form "L<fq-name>;"). AFAIR this can lead to the
situation that the type isn't loaded and therefore you cannot get its
type information. No idea if this is intended or an accident and should
be patched. Beyond that, to find the type one has to strip the L and
the ;, replace "/" by "." and  then use the resolver to find the type.
Perhaps this should be done by soot.
