[KISEMA-1534] Prio Java Code Generation produces wrong Behavior

[Issue KISEMA-1534 migrated from JIRA, first reported on 2019-11-11]

[Original links are dead as of 2022-05-11, links updated for new source files on 2022-05-17]

The java prio code generation produces code that fails the trace of this model: https://git.informatik.uni-kiel.de/ag-rtsys/kieler/models-private/-/blob/master/sccharts/simulation-tests/kolja/weak_suspend_simple.sctx
All other code generations (prio C and netlist) yield the correct behavior.

Please reactivate test when fixed by deleting the following property file: https://git.informatik.uni-kiel.de/ag-rtsys/kieler/models-private/-/blob/master/sccharts/simulation-tests/kolja/weak_suspend_simple.properties

kisema-1534.sctx

scchart WeakSuspension {
  input bool WS
  output int x
  
  weak suspend if WS

  initial state A
  do x += 1 go to B
  
  state B
  do x = 0 go to A
}

scchart WeakSuspension2 {
	input bool WS
	output int x
	bool _wsFlag = false
	int _WeakSuspension = 0
	bool _lastWishDone
	during do _wsFlag = WS
	immediate during do _lastWishDone = false

	state A {
		entry if !_wsFlag do _WeakSuspension = 0
	}
	do x += 1 go to B
	immediate if _wsFlag go to _WS

	state B {
		entry if !_wsFlag do _WeakSuspension = 1
	}
	do x = 0 go to A
	immediate if _wsFlag go to _WS

	state _WS {
		entry do _lastWishDone |= true
	}
	immediate if _WeakSuspension == 0 go to A deferred
	immediate if _WeakSuspension == 1 go to B deferred

	initial state _Init
	immediate if _wsFlag && _lastWishDone go to _WS
	immediate go to A
}

I think the updated links are https://git.informatik.uni-kiel.de/ag-rtsys/kieler/models-private/-/blob/master/sccharts/simulation-tests/kolja/weak_suspend_simple.sctx and https://git.informatik.uni-kiel.de/ag-rtsys/kieler/models-private/-/blob/master/sccharts/simulation-tests/kolja/weak_suspend_simple.properties respectively
