Dear Thredds community,

I recently upgraded my Tomcat from 6 to 7, Java from 1.6 to 1.88, Ferret
from 6.72 to 6.9, and Thredds from 4.2 to 4.3.

I get an error when trying to create a virtual variable. I use this URL
to create the variable:
http://localhost/thredds/dodsC/proj/forecast.nc_expr_{}{letdeq1%20speed=%28U^2%2BV^2%29^.5}.asc?speed

When I try to create virtual variable, I get the following error in the
logs:

java.lang.ClassCastException: [D cannot be cast to [F
