Error when building core.caos

[KevinPhemius]

Hi,

when I try to build the core, I have this issue with the tests of core.caos

13:23:16.806 [main] ERROR e.n.core.caos.CompositionManager - An exception occurred while handling shim message.

it doesn't happen every time, I have to relaunch the build multiple time for the test to pass.

Hi @KevinPhemius, it happens to me sometimes too. And as you mention, if I relaunch it, it usually builds successfully.
