[meirwah]

This seems to be blocking PR #30 in slang-content repo...

[orius123]

I think it is related to problem with serialization of Jython objects. and then recovery happens..
looking into it.

[meirwah]

@gseffy can you write which flow you run that causes this?

[gseffy]

consul/report_kv.sl
but I think it happens when the flow last task is python task...

[meirwah]

adding @Bonczidai , which sees similar issue in his Deis flow...

[orius123]

ok, so it seems that the issue is with upgrading jython to the latest beta..
still validating..

[meirwah]

@orius123 did you downgrade the Jython version?

[orius123]

now i did.
it solves most of those exceptions.
in loops we still have this exaptions though, opended CloudSlang/cloud-slang#137 to handle it.
