[Soot-list] Introducing the ASM Frontend for Soot

[Marc-André]

Alas, I've been having some exceptions using it.

a) TagBuilder, method visitAttribute().
This gave problem with some jars compiled by the Scala compiler because there
are some attributes
that are called 'Scala' or ScalaXYZ...

Suggested fix:
        if (attr.type.startsWith("Scala")) return;
		throw new UnsupportedOperationException("Unknown attribute: " + attr.type + "
for host" + host);

b) AnnotationElemBuilder method visit
I get the exception when 'value' is a boolean[2]. And I have no idea what it
means.

I don't like the idea of crashing when dealing with unknown annotations - does
it make sense to silently ignore them (or log a message?)

Regards,
