8.0-controls-scrum-h138: up to 27% footprint increase

    Details

      Description

      There is significant footprint and max memory usage increase in build 8.0-controls-scrum-h138.
      For example footprint of NodeMemory.Buttons was increased by 27%:
       #137: 5,100 objects
       #138: 3,700 objects -27% (-1,400.00)

      This also reduced runtime performance of some benchmarks.


      See all regression in Aurora:

      I have created heap dump files for 1000 Buttons for builds 137 and 138. Here is the list of additional objects
      which are created in case build 138 is used:

      Build 8.0-controls-scrum-h138 contains the following changes:
          1. branch merge (detail)
          2. RT-26554: if an inline style changes, clear the style cache so new styles will be recalculated. (detail)
          3. Fixed RT-23878: -fx-ellipsis-string doesn't apply after setStyle (detail)


      To reproduce the issue run for example NodeMemory.Button:
      > cd JFX_WS/tests/performance/NodeMemory
      > ant
      > java -Xms64m -Xmx64m -cp "JFX_HOME/rt/lib/jfxrt.jar;./dist/NodeMemory.jar"
        nodememory.NodeMemoryTest -shape button -render true -allocMax 1000

      to create heap dump file run with additional argument "-sleep true" and then use jmap to create heap dump file.
