> Disable RTTI `-GR-` for Hotspot when building with MSVC. This drops the size > of `jvm.dll` by roughly 1 MB. Hotspot does not rely on RTTI and it is > disabled for both GCC/Clang and Open XL C/C++ already. This change disables > it for MSVC, ensuring we do not accidently rely on RTTI for Windows-specific > code while also decreasing the resulting binary size. > > Cheers to @alexmenkov for finding the tricky root cause of why disabling RTTI > was causing a subset of serviceability agent tests to fail.
