**WTrayIconPeer**: removed duplicate call to `popupParent.dispose()` that might cause NPE (it looks `popupParent` cannot be `null`); organised imports.
**SystemTray**: removed redundant initialisers; replaced sized array with empty array in `toArray` call; dropped `newValue != null` chained with `equals`. ------------- Commit messages: - Resolve IDE warnings: redundant initializer, sized array in toArray - Remove 2nd call to popupParent.dispose() Changes: https://git.openjdk.java.net/jdk/pull/8850/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=8850&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8286663 Stats: 20 lines in 2 files changed: 8 ins; 4 del; 8 mod Patch: https://git.openjdk.java.net/jdk/pull/8850.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/8850/head:pull/8850 PR: https://git.openjdk.java.net/jdk/pull/8850
