RFR (S) 8144518: ClassVerboseTest crashes on Windows

[David Holmes]

Hi Coleen,

The bug report does not explain the problem so it is unclear whether 
this workaround is minimal. Also some commentary somewhere would be 
useful else the bug might return inadvertently - more generally I'd like 
to understand what other code might be impacted by this.

Thanks,
David
