[jdk17u-dev] RFR: 8305819: LogConfigurationTest intermittently fails on AArch64

[Liang Mao]

Hi all,

This pull request contains a backport of commit [911cc7cb](https://github.com/openjdk/jdk/commit/911cc7cb07ed44b24b4c20977d7d6e475bd1b234) from the [openjdk/jdk](https://git.openjdk.org/jdk) repository.


It fixed a logging crash due to arm weak memory model.

The commit being backported was authored by gaogao-mem on 15 May 2023 and was reviewed by Andrew Haley, David Holmes and Xin Liu.

The conflicts only come from the difference of "NULL" and "nullptr".

Additional testing:
- [x] Verified the test case in original PR.

Thanks!
