Description

### Affected version

3.5.4

### Bug description

Surefire adds the `--add-opens` option, which is not supported by Java 8, to the Java command when Java 9 or later is used as the JAVA_HOME directory.
``
Command was cmd.exe /X /C ""C:\Program Files\Java\openjdk\j9\jdk8u472-b08\bin\java.exe" --add-opens java.base/java.lang=ALL-UNNAMED --enable-native-access=ALL-UNNAMED ....
``
When using JDK 8 as the JAVA_HOME directory, everything works fine because the `--add-opens` option is not used.

Research direction

Reproduce a Java 8 toolchain project with JDK 9+ configured as JAVA_HOME and inspect how Surefire assembles the Java command. Verify the handling of --add-opens and --enable-native-access for the affected setup, then confirm the project builds successfully with appropriate regression coverage.
