Thu Feb 5 17:47:51 UTC 2026

Backporting JDK-8368892: Make JEditorPane/TestBrowserBGColor.java headless.

This PR convert TestBrowserBGColor.java to run headless by verifying background color programmatically instead of using Robot.getPixelColor to check screen pixels.

For parity with Oracle JDK.

Ran related tests on linux-x64, linux-aarch64, macos-aarch64 and windows-x64:

make test TEST=test/jdk/javax/swing/JEditorPane/TestBrowserBGColor.java
