Bug 82231 [build path] Hard to find type restriction compiler problem preferences
I20050104-1600 There compiler preference page contains a Warning/Error node with many sub-entries . I tried to find where I could change the 'warning' for the access of internal types to 'error'. No luck until I realized that the Build node also contains Warning/Error settings.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/preferences/BuildPathsPropertyPage.java
fBuildPathsBlock.initializeTimeStamps();

			} else {
				if (!fBuildPathsBlock.hasChangesInDialog() && fBuildPathsBlock.hasChangesInClasspathFile()) {
					fBuildPathsBlock.init(JavaCore.create(getProject()), null, null);
				}
			}
		}
		super.setVisible(visible);
