> On Mac ARM hardware running x86 JDK under Rosetta emulation, a div by 0 instruction causes the VM to crash.
> 
> The proposed fix (a workaround) for hotspot is to add **FPE_FLTINV** to the signal handler.
> 
> The actual fix needs to be done in macOS by Apple as the expected signal type here is **FPE_FLTDIV**
> This issue has been filed with Apple and they are tracking it.
