Re: tuscany could't support generic interface
Hi fzhong,
I see what you're saying... we do have some code to support generics, but
this seems to be a hole in our support.
It seems the function in JavaInterfaceUtil could maybe be improved to match
the operation correctly (and possibly some other piece of java interface
introspection might also need to be fixed).
Can you please open a JIRA, and attach your testcase?
