Bug 113239 new compiler option 'fatalOptionalError'
* COMPILER / Treating Optional Error as Fatal * When enabled, optional errors (i.e. optional problems which severity is set to "error") will be treated as standard * compiler errors, yielding problem methods/types preventing from running offending code until the issue got resolved. * When disabled, optional errors are only considered as warnings, still carrying an error indication to make them more * severe. Note that by default, errors are fatal, whether they are optional or not. * - option id: "org.eclipse.jdt.core.compiler.problem.fatalOptionalError" * - possible values: { "enabled", "disabled" } * - default: "enabled" </pre>
