> Hi, this is an almost clean backport of openjdk/jdk17u-dev#3901.
> 
> The only differences are in context (deleted and surrounding code) due to 11u missing [JDK-8211300: Convert C-style array declarations in JDK client code](https://bugs.openjdk.org/browse/JDK-8211300).
> 
> NOTE: as part of this work, I found some issues with the original patch (see [JDK-8373727](https://bugs.openjdk.org/browse/JDK-8373727 "New XBM images parser regression: only the first line of the bitmap array is parsed")), so an additional backport of that fix will be needed too.
> 
> #### Testing
> 
> The [GitHub Actions testing run (tier1 on various platforms)](https://github.com/franferrax/jdk11u-dev/actions/runs/20177700844) has passed.
> 
> In addition, the new `test/jdk/java/awt/image/XBMDecoder/XBMDecoderTest.java` is passing in a local slowdebug build on _Fedora Linux x64_.
