Have you downloaded bytecode.jar? (the most recent version
of this is available from our binary download site). Some
parts of BioJava use on-the-fly code generation techniques,
and require this library to be available on your CLASSPATH.
The exception you posted suggests that this is missing.

No, the `name' property of a SimpleSequence can only be
set at construction time. This could probably changed if
there was a good reason, though.

By `annotation' do you mean the set of metadata in
the header which is not the feature table? The BioJava
parsers do extract this information from the file, and
store it in an Annotation object. However, very little
of it currently gets re-exported by the EMBL writer.
It shouldn't be too bad a job to add the code to write
this data, but it probably requires more familiarity
with the details of the EMBL format than I can offer...
