Should we allow use Unsafe or ByteArrayLittleEndian for trivial byte[] writes
in core-libs？
There is already code that uses ByteArrayLittleEndian to improve performance,
such as:
```java
package java.util;
class UUID {
public String toString() {
// ...
ByteArrayLittleEndian.setInt(
buf,

I believe this has introduced a build failure with GCC 12.2 on Debian 12.1:
Building target 'jdk' in configuration '/home/fw/build/jdk'
In file included from /usr/lib/gcc/x86_64-linux-gnu/12/include/immintrin.h:49,
from
…/jdk/src/java.base/linux/native/libsimdsort/avx512-common-q
I’ve been investigating a problem with a long running application that
accumulates an apparently unbounded number of
CVDisplayLink threads. I do not yet have an explanation or a test case.
The code that creates and releases CVDisplayLinks looks fine, but that assumes
there are no threading issue
