I don't think this is an SPL specification issue. This is strictly a
problem with the definition of the method's return type as indicated in
the Java Class object. Somehow that definition is not being picked up as
an array and instead just as a single byte. It _is_ getting the formal
parameter definition correct (i.e. a byte[]).

Re: [jira] Updated: (IMPERIUS-28) byte[] method return type does not match
formal parameter
David,
It seems to me that Imperius is not capable of handling array return type
because the SPL does not distinguish between primitive return type and
array return type syntactically.

> It appears that a method's byte[] return type is not being properly
matched with a byte[] method argument. The attached Java program includes
a policy that passes the byte[] return value of a method to another method
that expects the same. This gives the following message:
