Intermediate timer catch event is executed twice

[abounader10]

i have a non consistent behavior regarding intermediate timer catch event.

i have a timer event followed by a flow, this timer event is triggered after a specific time duration. sometimes when it is triggered and the flow after it reaches a waiting or an end state, at that moment the timer event is executed again immediately and rerun the flow until it stops at the waiting state.

i am using Activiti-engine-6.0.0 with spring boot application.
