KIE-Sandbox DMN execution is broken after applying accelerator if the executed model imports another model

[jaimeizuz]

Hello,

the execution of a DMN model that imports another DMN model in the same project in KIE-Sandbox is broken after applying the Quarkus accelerator (tested with other custom accelerators as well, the issue is reproduced).

Before applying the accelerator everything works fine.

It's reproducer in v0.32.0 and daily-dev as well.

Steps to reproduce:

• Clone this repo with the KIE-Sandbox UI
• Run the RepetirExamenLicenciaDecision model. The form is generated and execution works fine.
• Apply the Quarkus Accelerator
• Run the RepetirExamenLicenciaDecision model again. The form is not generated anymore, showing an error panel in the UI.

I've attached the logs I see in the extended-services container. dmn-runner-error.log

@thiagoelg @tiagobento I tested it against the current version in main. It reproduces partially, in detail: after applying the accelerator, the DMN runner form shows an error for ~1 - 2 seconds, but thereafter the DMN runner works again.

If the behavior is confirmed, I would classify it as an improvement and not a bug. Instead of that error, I would show a loading message or something similar. As an alternative, we can just close the DMN Runner drawer
