[jdk11u-dev] RFR: 8261916: gtest/GTestWrapper.java vmErrorTest.unimplemented1_vm_assert failed

[Thomas Stuefe]

Hi,

I'd like to backport "JDK-8263728: gtest/GTestWrapper.java vmErrorTest.unimplemented1_vm_assert failed", since it prevents sporadic gtest errors.

Original commit: https://github.com/openjdk/jdk/commit/8c1112a6

This one is not a clean backport:
- `vmError.cpp` changed slightly, since https://bugs.openjdk.java.net/browse/JDK-8258479 did some code cleanups for JDK17
- more importantly, this patch touches `os::abort()`. That function had been unified into `os_posix.cpp` for all posix platforms with https://bugs.openjdk.java.net/browse/JDK-8263564 for JDK 17. I briefly considered backporting JDK-8263564, but decided against it since it is too invasive and unnecessary. Instead, I changed the various os::abort() implementations for all individual OSes, including Solaris.

Tests: Nightlies at SAP, GHAs.

Thanks, Thomas
