It seems that the org.eclipse.jdt.core.compiler.problem.fatalOptionalError=enabled causes the compiler to ignore statement scope @SuppressWarnings annotations. > cat bad.prefs org.eclipse.jdt.core.compiler.codegen.targetPlatform=1.8 org.eclipse.jdt.core.compiler.compliance=1.8 org.eclipse.jdt.core.compiler.problem.fatalOptionalError=enabled org.eclipse.jdt.core.compiler.problem.rawTypeReference=error org.eclipse.jdt.core.compiler.problem.suppressOptionalErrors=enabled org.eclipse.jdt.core.compiler.problem.suppressWarnings=enabled org.eclipse.jdt.core.compiler.source=1.8 > cat Test.java public class Test { public static void main(String[] args) { @SuppressWarnings("rawtypes") Class<? extends Enum> enumClass = null; System.out.println(enumClass); } } > java -jar ecj-4.6.3.jar -properties bad.prefs Test.java && java Test Exception in thread "main" java.lang.Error: Unresolved compilation problem: Enum is a raw type.

I can't reproduce with latest 4.7 build - I20170508-2000. Note, I had only the preferences you had specified. So not sure if there are any other factors involved. Doug, can you try the build I mentioned?
I can still reproduce with ecj-4.7M6.jar and ecj-I20170508-2000.jar: > java -version java version "1.8.0_121" Java(TM) SE Runtime Environment (build 1.8.0_121-b13) Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode) > java -jar ~/Downloads/ecj-4.7M6.jar -properties bad.prefs Test.java && java Test Exception in thread "main" java.lang.Error: Unresolved compilation problem: Enum is a raw type.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
I can reproduce. Not good, suppressOptionalErrors allows to make the error invisible, but fatalOptionalError lets it crash at runtime. To be consistent, ecj should decide to either 1. disallow suppressing fatal errors, or 2. let @SW suppress optional problems even when configured as fatal Option 2. is being requested and I second that motion. It implies that only non-suppressed optional problems are fatal, of course.
