        A couple of tests e.g. VendorInfoPluginsTest but also some Hotspot like runtime/ErrorHandling/CreateCoredumpOnCrash.java put (write) to special addresses like 0 to provoke crashs.
        However this does not work well with ubsan-enabled binaries on the clang based platforms (macOS, AIX).
        The mentioned tests generate a SIGSEGV.

        Some other tests generate a SIGBUS, e.g.
        runtime/memory/ReserveMemory.java
        runtime/memory/ReadFromNoaccessArea.java
        and this leads to similar issues with ubsan-enabled binaries.

        We should adjust the signal handling with the sanitizer options, how to do this is documented here :
