[jdk17u-dev] RFR: 8294316: SA core file support is broken on macosx-x64 starting with macOS 12.x

Wed Dec 18 20:13:57 UTC 2024

A clean backport of [JDK-8294316](https://bugs.openjdk.org/browse/JDK-8294316) to properly parse core files in macOS 12 and later. Load commands with length zero are now discarded.

The fix doesn't affect directly to SA tests in 17, but it's being backported to 11 as this is the cause of https://github.com/openjdk/jdk11u-dev/pull/2967#issuecomment-2538048579.

Tests in 17 continue to pass in all platforms, including macos.
