The test runs out of heap space for me on Windows with or without your fix using the default heap size. This may point to a leak, although bumping up the memory causes it to pass with your fix. The fix looks good, although the test doesn't catch the bug most of the time (even when bumping up the heap). ------------- PR Review: https://git.openjdk.org/jfx/pull/1698#pullrequestreview-2600480255
