Fix request [11u,17u] I backport this for parity with 11.0.17-oracle,17.0.5-oracle. A smaller change in win only coding, limited risk. will only affect awt. Above mentioned changes are already backported. Clean backport. Test passes on win and fails without the fix. SAP nightly testing passes.

The test for this fix uses PassFailJFrame, the manual test framework, which was recently added. Backporting the fix requires backporting these two changesets: 1. JDK-8284535: Fix PrintLatinCJKTest.java test that is failing with Parse Exception 2. JDK-8283712: Create a manual test framework class 3. JDK-8283803: Remove jtreg tag manual=yesno for java/awt/print/PrinterJob/PrintGlyphVectorTest.java and fix test 4. JDK-8284898: Enhance PassFailJFrame The CRs are combined into pairs.

There are two issues associated with trayicon issue 1. Scaling issue - which is fixed. 2. Timing issue - as multiple events are triggered on DPI change event the updation of the trayicon needs to be timed properly and triggered only when all WM_POSCHANGING events are done. Work is in progress for the timing issue.

Yes, it is a simple fix for the HiDPI environment.
