I tested the following on clojure 1.2 and clojure 1.2.1 and it
does not seem to work.
(def foo (agent nil))
(def bar (agent nil :error-handler (fn [a e] (do (def called? true)
(send foo (constantly e)))))
(def called? false)
(send bar inc) ; try incrementing nil
(await error) ; wait for agent to finish
[@foo called?] ; check value
=> [nil true]
The last expression should evaluate to: [true
#<NullPointerException java.lang.NullPointerException>]. Instead, it's
evaluating to '[nil true]', which indicates that the 'error-handler'
is indeed being called but 'send' isn't working.
It works as expected on clojure 1.3.0-beta1 though.
Seems like this issue was reported last year and has resurfaced.
