Scenario
- Process with a TimerStartEvent on a EventSubprocess
- TimerStartEvent uses expression for the timer duration, like ${duration}
- process instance is started with timer epxression variable (duration = "PT1S")
- Process instance starting fails
- The following exception is printed
org.camunda.bpm.engine.ProcessEngineException: Unknown property used in expression: ${duration}. Cause: Cannot resolve identifier 'duration'

Expected
No exception is thrown, timer can be evaluated and timer start event can occur.
Problem
In the PvmExecutionImpl the timer declarations are initialized before the variables are set.
