code generation styles, C and Java??

I'm trying to setup some tasks that can benchmark
size and speed for all the different ragel code
generation styles.
In my RakeFile I've got these constants defined:
RAGEL_CODE_GENERATION_STYLES = {
"table_driven" => 'T0',
"faster_table_driven" => 'T1',
"flat_table_driven" => 'F0',
"faster_flat_table_driven" => 'F1',
"goto_driven" => 'G0',
"faster_goto_driven" => 'G1',
"really_fast goto_driven" => 'G2'
# "n_way_split_really_fast_goto_driven" => 'P<N>'
}
DEFAULT_RAGEL_CODE_GENERATION = "really_fast goto_driven"
I assume they can all be used with C generation.
The manual states:
In the case of Java and Ruby, table-based code generation is the
only code style supported.
There appear to be two types of table-base code generation:
-F0 þat table-driven
-F1 þat table, expanded actions
But neither of these works:
ragel -J -F0 -o test.java test.rl
ragel -J -F1 -o test.java test.rl
Only this:
ragel -J -o test.java test.rl
Is there only one style of Java code generation?
