Thiago H. de Paula Figueiredo commented on TAP5-2582:
-----------------------------------------------------
Thanks for reporting this, [~thomas303]!
Tapestry-IoC and Plastic were adding the proxy method to delegate to the
service implemenation object once per {{close()}} method in the interfaces,
causing the exception above. The fix was basically preventing this to happen,
plus making sure the proxy method has all the thrown exceptions for each method
with the same signature.
