A lot of errors "Java Model Exception: Java Model Status" since migrating to Katalon 7.6.2

Hello,
since some time now (I think since I migrated katalonc.exe to version7.6.2), I have a lot of error messages which are filling my console.
Here is a sample of one of these error messages :

[2020-08-25T21:30:48.264] Java Model Exception: Java Model Status [1 [in ReflexShare [in ReflexShare.groovy [in test.common [in Keywords [in D%%Tools%Jenkins%workspace%Cimsup kanban 9.14%reflexCoreModel.prj]]]]] does not exist]

It seem it generate this message for every classes of my Keywords libraries :

Do you know where it could come from ?

Here is complete log from Jenkins :
katalon_log_error.txt (94.8 KB)

Hi @staniere,
Is this just the warning or it terminates your test execution?

Hi Huynguyen, this is only a warning. My execution goes normally after these warnings.
