Hi, this pull request contains:

* 8a4de7e8f8523b2fd9e492bc57bac5c7c9a7e115: a clean [JDK-8361748](https://bugs.openjdk.org/browse/JDK-8361748 "Enforce limits on the size of an XBM image") backport from openjdk/jdk11u-dev at 4e9144c
* fb27ada8e6668ef915725a780d2f37c13c390be1: a clean [JDK-8373727](https://bugs.openjdk.org/browse/JDK-8373727 "New XBM images parser regression: only the first line of the bitmap array is parsed") backport from openjdk/jdk11u-dev at 99d39c924322594a7cf4940b95cd0e4a75c6fd12
* 64d624cb61c369a9d753a12b7e862e37e7855aa6: adjustments required for 8u (due to unavailable APIs and the changed test path)

#### Testing

* The new `jdk/test/java/awt/image/XBMDecoder/XBMDecoderTest.java` is passing in a local Linux x64 build
* [GHA run](https://github.com/franferrax/jdk8u-dev/actions/runs/21674111373) Linux failures in `hotspot/tier1` and `jdk/security_infra` are unrelated to this change:
    * `hotspot/test/compiler/5091921/Test7005594.java`
    * `jdk/test/security/infra/java/security/cert/CertPathValidator/certification/CAInterop.java`
