[midPoint] OperationResult memory leaking, "No ScriptExpressionEvaluationContext for current thread found."

[Forest Crowley]

Hi Pavol,

Thanks for looking into this. I created a ticket in the Evolveum Jira, here
is a link to it: https://jira.evolveum.com/browse/MID-6145 . I was able to
do some further troubleshooting and included additional details and a
sample. Setting workerThreads to 0 did not seem to help.

Thanks!

Forest
