No I did not try Oracle Java6 and it would be a real hassle since it's
not even installed...I think I've got openJDK 6 though...hmm I'll poke
around with the dependencies of the namespace I'm trying to load see if
that changes anything and if it doesn't I'll give openJDK a spin...
Clojure seems rather sure it is my record definition...but if I try to
load the namespace containing the record everything is fine...it is the
'consumer' namespace (workflows.clj) that doesn't load (sometimes)...

Did you try with Java 6 ? I am inclined that your problem is not so much with
your code than with one of your java dependencies.

I just walked in home, sat on my pc, /git-pull/ (what I pushed 30 min
ago), /lein2 repl/, /load-file xxx.clj/ , *BOOM!*
CompilerException java.lang.VerifyError: (class:
hotel_nlp/concretions/models/Workflow, method: run signature:

this is beyond belief! I thought I sorted that at the office...before
leaving I tried lein2 repl/lein2 test 5 times and it worked every single
time!!!!

My actual project has practically no dependencies! All that stuff I need
to test what I'm doing. I'm providing the glue (the protocols and the
extension-points) for several NLP libraries...after I'm done with each
library, I need to pull it in and use it exactly as a consumer would. At
the moment I've only done openNLP , stanfordNLP & GATE so it is normal
to see those and their dependencies in the dep-tree. They are used in
examples/workflows.clj which demonstrates how the 'glue' feels like from
a consumer's perspective...
any help to get to the bottom of this will be really appreciated
guys...This is a rather ambitious project but I'd like for it to step on
its feet quite early....I can't do anything while this persists...I
mean, I can but it is eating my brain...

Hi,
can you post the JVM used, maybe a snippet of the code around line 68,
the dependencies tree (lein deps :tree) and your project.clj ?
With these we can probably find the root cause of this.
Luc P.
Hi Luc,
thanks for your interest but I think I've cracked it...:) the code
that was causing this is the following record. You will notice that
'deploy' delegates to 'run' per component. But then, since a WorkFlow
can be a Component as well, the 'run' fn should NOT delegate to
'deploy' as it will only go round in circles!
So, from what I understand '(deploy this text)' should be '(reduce
#(run %2 %) text components))' which is basically what 'deploy' does!
This is in-line with what Marko / Meikel suggested...
(defrecord Workflow [components] ;;a seq of components - the workflow
can itself be a component
IWorkflow
(getComponents [this] components) ;;just return all components
(appendComponent [this c] (conj (vec components) c))
(addComponent [this pos c] (addC components pos c))
(removeComponent [this pos] (removeC components pos))
(replaceComponent [this pos replacement] (replaceC components pos
replacement))
(deploy [_ text intermediates?]
((if intermediates? reductions reduce)
(fn [init c] (run c init)) text components))
(deploy [this text] (deploy this text false))
;(deploy [this] (deploy this))
IComponent
(link [this pos other]
(Workflow. (help/link this pos other)))
;(run [this] (deploy this))
(run [this text] (deploy this text) ;(reduce #(run %2 %) text components))
;(run [this text & more] (deploy this text (first more)))
clojure.lang.IFn ;;can act as an fn
(invoke [this arg]
(deploy this arg))
(applyTo [this args]
(apply deploy this args)) ) Jim
