Fixed a memory leak in TreeTableView by using WeakInvalidationListener (which is the right approach in this particular situation) - the leak is specific to TreeTableRowSkin.
Added a unit test. Added Refresh buttons and Skin menu to the Monkey Tester (will expand these to other controls as a part next MT update). ------------- Commit messages: - whitespace - updated test - variable tree cell fix - fixed size selector - list view page - fix and test - skin menu - refresh button Changes: https://git.openjdk.org/jfx/pull/1129/files Webrev: https://webrevs.openjdk.org/?repo=jfx&pr=1129&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8307538 Stats: 202 lines in 7 files changed: 160 ins; 15 del; 27 mod Patch: https://git.openjdk.org/jfx/pull/1129.diff Fetch: git fetch https://git.openjdk.org/jfx.git pull/1129/head:pull/1129 PR: https://git.openjdk.org/jfx/pull/1129
