[jdk25u-dev] RFR: 8358058: sun/java2d/OpenGL/DrawImageBg.java Test fails intermittently

Thu Feb 12 20:47:59 UTC 2026

Backporting JDK-8358058: sun/java2d/OpenGL/DrawImageBg.java Test fails intermittently.

This PR migrates tests from a closed repository with improvements including corrected thread logic, paint-on-demand behavior, and support for all systems (not just OpenGL).

For parity with Oracle JDK.

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

make test TEST=test/jdk/sun/java2d/OpenGL/DrawBitmaskImage.java
make test TEST=test/jdk/sun/java2d/OpenGL/DrawBufImgOp.java
make test TEST=test/jdk/sun/java2d/OpenGL/DrawImageBg.java
make test TEST=test/jdk/sun/java2d/OpenGL/LargeOps.java
make test TEST=test/jdk/sun/java2d/OpenGL/OpaqueDest.java
make test TEST=test/jdk/sun/java2d/OpenGL/ScaleParamsOOB.java
make test TEST=test/jdk/sun/java2d/OpenGL/ShapeClip.java
make test TEST=test/jdk/sun/java2d/OpenGL/SrcMaskOps.java
make test TEST=test/jdk/sun/java2d/OpenGL/VolatileSubRegion.java
make test TEST=test/jdk/sun/java2d/OpenGL/XformVolatile.java

Note: test/jdk/sun/java2d/OpenGL/ScaleParamsOOB.java fails on linux-x64 and linux-aarch64 with a color mismatch error (expected=ffff0000 actual=ff000000 at x=40 y=40), similar to [JDK-8369335](https://bugs.openjdk.org/browse/JDK-8369335). This will be fixed in a separate backport PR.
