RFR 8009517: Disable fatal compiler warning in the old build

[Chris Hegarty]

Since the new build does not enable -Werror when compiling any java 
code, and disables quite a few lint options, new changes my 
inadvertently introduce warnings without even realizing. This can cause 
problems when building with the old build as many areas do compile with 
-Werror set. Since the old build is on life support, probably best to 
just completely disable -Werror, so anyone still needing to use it can.
