The `null` check creates a new Array but always assumed a non-empty one which may lead to ``` java.lang.ArrayIndexOutOfBoundsException: Index 0 out of bounds for length 0 at org.enso.runtime/org.enso.interpreter.service.ExecutionService$FunctionPointer.collectNotAppliedArguments(ExecutionService.java:778) at org.enso.runtime/org.enso.interpreter.instrument.job.ProgramExecutionSupport$.sendExpressionUpdate(ProgramExecutionSupport.scala:430) at org.enso.runtime/org.enso.interpreter.instrument.job.ProgramExecutionSupport$.$anonfun$executeProgram$3(ProgramExecutionSupport.scala:81) at org.enso.runtime/org.enso.interpreter.service.ExecutionCallbacks.callOnComputedCallback(ExecutionCallbacks.java:146) at org.enso.runtime/org.enso.interpreter.service.ExecutionCallbacks.updateCachedResult(ExecutionCallbacks.java:117 ... ``` Added a guard to prevent the exception. The flag will be useless anyway as we won't enter the for-loop in this case.
