Applet FX Thread not respecting order of runnables when loading FXML

    XMLWordPrintable

    Details

    • Type: Bug
    • Status: Closed
    • Priority: P4
    • Resolution: Won't Fix
    • Affects Version/s: 7u45, 8, 9
    • Fix Version/s: None
    • Component/s: javafx
    • Environment:

      java 1.7.0_45-b18 32 bits, IE, FF, Windows (7 & 8 at least)

      Description

      Scenario :
      - execute two tasks successively with Platform.runLater()
      - first one loads a FXML and affects the FXML controller to an attribute
      - second one accesses to this attribute

      Platform.runLater() doc says "The Runnables are executed in the order they are posted. " so I'm expecting to have no problem accessing the attribute in the second runnable.
      http://docs.oracle.com/javafx/2/api/javafx/application/Platform.html#runLater%28java.lang.Runnable%29

      When deploying as an applet I get a NPE. It didn't happen with all previous versions.

      I'm posting the sample test right after this.

      Certainly related to https://javafx-jira.kenai.com/browse/RT-33657
      Here is the NPE stack trace :
