— based on offline help:
“For some other types of problems you can, however, specify if you want the Java compiler to report them as warnings, errors or to ignore them. To change the default settings, use the Java > Compiler > Errors/Warnings preference page.”
Suggestion (untested): During rush phase, many of your colleagues would probably ignore the hundreds of warnings anyway. On the config window, Try to turn every listed item from “warning” to “ignore”. May reduce noise. When you want to work on your code quality, you may wnat to turn on specific items.
