Fixing a memory leak. A node hard references its old parent after CSS layout and getting removed. This shouldn't be the case, this is very counterintuitive.
The fix uses a WeakReference in CSSStyleHelper for firstStyleableAncestor. This should be fine because the CSS should only depend on it if it's still the real parent. In that case, it doesn't get collected. ------------- Commit messages: - 8263402 Changes: https://git.openjdk.java.net/jfx/pull/424/files Webrev: https://webrevs.openjdk.java.net/?repo=jfx&pr=424&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8263402 Stats: 116 lines in 2 files changed: 107 ins; 0 del; 9 mod Patch: https://git.openjdk.java.net/jfx/pull/424.diff Fetch: git fetch https://git.openjdk.java.net/jfx pull/424/head:pull/424 PR: https://git.openjdk.java.net/jfx/pull/424
