node.impl_processCSS can lead to infinite loop

    Details

    • Type: Bug
    • Status: Closed
    • Priority: P3
    • Resolution: Cannot Reproduce
    • Affects Version/s: fx2.0
    • Fix Version/s: 7-pool
    • Component/s: javafx
    • Environment:

      Windows, Mac

      Description

      In the VT, in order to force CSS Engine to bootsrap, we are calling this internal method. We do understand that it is not a supported API.
      In some cases, diffcult to isolate, we are entering into an infinite loop and a bunch of stacks are displayed (some ClassCast exceptions.).

      I am copying a subset of the traces logged when we do enter the infinite loop.

      Calling impl_reapplyCSS in the next tick (thanks to a timeline keyframe), we do not enter the inifinite loop.
