JDK-8202084 - [win] IME candidate window wrong position
Description
This is the Swing equivalent of JDK-8189282.

To reproduce this bug, use the Japanese IME on Windows 10 with the display set to 125% or 150% and run any Swing program that has a JTextField or JTextArea (e.g., the attached program). When you enter text using the IME popup, the popup will be positioned above and to the left of where it should be, obscuring the text field.

[jdk8u-fix-request] Approval Request from ktakakuri This bug is reproducible in JDK8, and backporting this patch is needed. JDK-8189687 contains two fixes to AwtComponent:.OpenCandidateWindow, one of which is backported in this pull request. The other fix is an enhancement to JEP 263 (JDK-8055212) and is not needed since JDK8 does not implement JEP 263.

I am not able to reproduce this issue in jdk10. The text are inputted inline on-the-spot.

Did you try it on a Windows machine with a 125% or 150% scaling?

As with the JavaFX bug, the IME popup obscures what is being typed making it very difficult to use.
