Its a limitation in the Java bytecode format itself:
A method can have only 64k bytecode instructions.
A workaround would be to split the code up in several methods.
However, I think we first should look if the rule could be simplified or
something. as 64 thousand bytecode instructuions probably means the rule
contains over 5000-10000 comparisons and invocations, which I'd is way too
much
Jimmy, could you pastebin ./apertium_es_ast_es_ast_t1x.java somewhere so we
could have a look.
