I have received via this list and personal e-mail two interpretations of the
proper opcodes. Will the next release fix this and the attribute field
length inconsistency?
Also, what about the version field? The spec says that it should be a u4
containing the number 45 and that any other number means that it is
incompatible. But when I look at a class file, there is a u4 containing
"0002002D". The last u2 of this is 45, but what about that other u2 containing
2? Could this be actually a u2 with a version and a u2 with an update, where
update is unimportant change and version is incompatible change? It would be
nice if the spec spelled out what this means.
